These gates can be implemented using adiabatic or non adiabatic processes. Adiabatic models can be controlled using auxiliary qubits, whereas non adiabatic models can be simplified by using one single-shot implementation. In this paper, the controlled adiabatic evolutions is combined with the single-shot implementation to obtain quantum gates with controlled non adiabatic evolutions. This is an important improvement which can speed the implementation of quantum gates and reduce the errors due to the long run in the adiabatic model. The robustness of our scheme to different types of errors is also investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Adiabatic%20evolutions" title="Adiabatic evolutions">Adiabatic evolutions</a>, <a href="https://publications.waset.org/search?q=non%20adiabatic%20evolutions" title=" non adiabatic evolutions"> non adiabatic evolutions</a>, <a href="https://publications.waset.org/search?q=controlled%20adiabatic%20evolutions" title=" controlled adiabatic evolutions"> controlled adiabatic evolutions</a>, <a href="https://publications.waset.org/search?q=quantum%20rotation%20gates" title=" quantum rotation gates"> quantum rotation gates</a>, <a href="https://publications.waset.org/search?q=dephasing%0D%0Arates" title=" dephasing rates"> dephasing rates</a>, <a href="https://publications.waset.org/search?q=master%20equation." title=" master equation."> master equation.</a> </p> <a href="https://publications.waset.org/10008506/implementation-of-quantum-rotation-gates-using-controlled-non-adiabatic-evolutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10008506/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10008506/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10008506/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10008506/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10008506/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10008506/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10008506/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10008506/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10008506/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10008506/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10008506.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1167</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">75</span> A Single-Phase Register File with Complementary Pass-Transistor Adiabatic Logic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jianping%20Hu">Jianping Hu</a>, <a href="https://publications.waset.org/search?q=Xiaolei%20Sheng"> Xiaolei Sheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces an adiabatic register file based on two-phase CPAL (Complementary Pass-Transistor Adiabatic Logic circuits) with power-gating scheme, which can operate on a single-phase power clock. A 32×32 single-phase adiabatic register file with power-gating scheme has been implemented with TSMC 0.18μm CMOS technology. All the circuits except for the storage cells employ two-phase CPAL circuits, and the storage cell is based on the conventional memory one. The two-phase non-overlap power-clock generator with power-gating scheme is used to supply the proposed adiabatic register file. Full-custom layouts are drawn. The energy and functional simulations have been performed using the net-list extracted from their layouts. Compared with the traditional static CMOS register file, HSPICE simulations show that the proposed adiabatic register file can work very well, and it attains about 73% energy savings at 100 MHz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Low%20power" title="Low power">Low power</a>, <a href="https://publications.waset.org/search?q=Register%20file" title=" Register file"> Register file</a>, <a href="https://publications.waset.org/search?q=Complementarypass-transistor%20logic" title=" Complementarypass-transistor logic"> Complementarypass-transistor logic</a>, <a href="https://publications.waset.org/search?q=Adiabatic%20logic" title=" Adiabatic logic"> Adiabatic logic</a>, <a href="https://publications.waset.org/search?q=Single-phase%20power%20clock." title=" Single-phase power clock."> Single-phase power clock.</a> </p> <a href="https://publications.waset.org/2512/a-single-phase-register-file-with-complementary-pass-transistor-adiabatic-logic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/2512/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/2512/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/2512/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/2512/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/2512/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/2512/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/2512/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/2512/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/2512/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/2512/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/2512.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1965</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">74</span> Rating Charts of R-22 Alternatives Flow through Adiabatic Capillary Tubes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=E.%20Elgendy"> E.

The present paper aims at design adiabatic capillary tubes for R-22 alternatives such as R-417A, R-422D and R-438A. A theoretical model has been developed and validated with the available experimental data from literature for R-22 over a wide range of both operating and geometrical parameters. Predicted lengths of adiabatic capillary tube are compared with the lengths of the capillary tube needed under similar experimental conditions and majority of predictions are found to be within 4.4% of the experimental data. Hence, the model has been applied for R-417A, R- 422D and R-438A and capillary tube selection charts and correlations have been computed. Finally a comparison between the selected refrigerants and R-22 has been introduced and the results showed that R-438A is the closest one to R-22. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Adiabatic%20flow" title=" Adiabatic flow"> Adiabatic flow</a>, <a href="https://publications.waset.org/search?q=Capillary%20tube" title=" Capillary tube"> Capillary tube</a>, <a href="https://publications.waset.org/search?q=R-22%20alternatives" title=" R-22 alternatives"> R-22 alternatives</a>, <a href="https://publications.waset.org/search?q=Rating%20charts" title=" Rating charts"> Rating charts</a>, <a href="https://publications.waset.org/search?q=Modelling." title=" Modelling."> Modelling.</a> </p> <a href="https://publications.waset.org/16117/rating-charts-of-r-22-alternatives-flow-through-adiabatic-capillary-tubes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/16117/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/16117/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/16117/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/16117/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/16117/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/16117/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/16117/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/16117/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/16117/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/16117/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/16117.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3294</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">73</span> Complementary Energy Path Adiabatic Logic based Full Adder Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Shipra%20Upadhyay">Shipra Upadhyay </a>, <a href="https://publications.waset.org/search?q=R.%20K.%20Nagaria"> R.

To decrease leakage consumption is becoming more and more important in low-power design. This paper presents a power-gating scheme for P-DTGAL (p-type dual transmission gate adiabatic logic) circuits to reduce leakage power dissipations under deep submicron process. The energy dissipations of P-DTGAL circuits with power-gating scheme are investigated in different processes, frequencies and active ratios. BSIM4 model is adopted to reflect the characteristics of the leakage currents. HSPICE simulations show that the leakage loss is greatly reduced by using the P-DTGAL with power-gating techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Leakage%20reduction" title="Leakage reduction">Leakage reduction</a>, <a href="https://publications.waset.org/search?q=low%20power" title=" low power"> low power</a>, <a href="https://publications.waset.org/search?q=deep%20submicronCMOS%20circuits" title=" deep submicronCMOS circuits"> deep submicronCMOS circuits</a>, <a href="https://publications.waset.org/search?q=P-type%20adiabatic%20circuits." title=" P-type adiabatic circuits."> P-type adiabatic circuits.</a> </p> <a href="https://publications.waset.org/7685/a-power-gating-scheme-to-reduce-leakage-power-for-p-type-adiabatic-logic-circuits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7685/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7685/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7685/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7685/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7685/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7685/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7685/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7685/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7685/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7685/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7685.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1934</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">71</span> Global Behavior in (Q-xy)2 Potential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=K.%20Jaroensutasinee">K.

It is soluble in water and in many organic solvents. PEG is used to make emulsifying agents, detergents, soaps, plasticizers, ointments etc. Ethanol (C<sub>2</sub>H<sub>5</sub>OH) also known as ethyl alcohol is a well-known organic compound and has wide applications in chemical industry as it is used as a solvent for paint, varnish, in preserving biological specimens, used as a fuel mixed with petrol etc. Though their chemical and physical properties are already studied, still because of their uses in day to day life the authors thought it is better to study some more of their physical properties like ultrasonic velocity and hence adiabatic compressibility, free length, etc. A detailed study of such properties and some excess parameters like excess adiabatic compressibility, excess free volume and few more in the liquid mixtures of these two compounds with PEG as a solute and Ethanol as a solvent at various mole fractions may throw some light on deeper understanding of molecular interaction between the solute and the solvent supported by NMR, IR etc. Hence the present research work is on ultrasonics/allied studies on these two liquid mixtures. Ultrasonic velocity (U), density (&rho;) and viscosity (&eta;) at room temperature and at different mole fraction from 0 to 0.055 of ethanol in PEG have been experimentally carried out by the authors. Acoustical parameters such as adiabatic compressibility (&beta;), free volume (V<sub>f</sub>), acoustic impedance (Z), internal pressure (&pi;<sub>i</sub>), intermolecular free length (L<sub>f</sub>) and relaxation time (&tau;) were calculated from the experimental data. We have calculated excess parameters like excess adiabatic compressibility (&beta;<sup>E</sup>), excess internal pressure (&pi;<sub>i</sub><sup>E</sup>) free length (L<sub>f</sub><sup>E</sup>) and excess acoustic impedance (Z<sup>E</sup>) etc for these two chosen liquid mixtures. The excess compressibility is positive and maximum around a mole fraction 0.007 and excess internal pressure is negative and maximum at the same mole fraction and longer free length. The results are analyzed and it may be concluded that the molecular interactions between the solute and the solvent is not strong and it may be weak. Appropriate graphs are drawn.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Adiabatic%20Compressibility" title="Adiabatic Compressibility">Adiabatic Compressibility</a>, <a href="https://publications.waset.org/search?q=Binary%20mixture" title=" Binary mixture"> Binary mixture</a>, <a href="https://publications.waset.org/search?q=Induce%20dipole" title=" Induce dipole"> Induce dipole</a>, <a href="https://publications.waset.org/search?q=Polarizability" title=" Polarizability"> Polarizability</a>, <a href="https://publications.waset.org/search?q=Ultrasonic." title=" Ultrasonic."> Ultrasonic.</a> </p> <a href="https://publications.waset.org/9998122/ultrasonic-investigation-of-molecular-interaction-in-binary-liquid-mixture-of-polyethylene-glycol-with-ethanol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9998122/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9998122/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9998122/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9998122/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9998122/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9998122/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9998122/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9998122/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9998122/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9998122/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9998122.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2784</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> Energy Efficiency Analysis of Discharge Modes of an Adiabatic Compressed Air Energy Storage System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Shane%20D.%20Inder">Shane D.

Among the many options available for energy storage systems required to balance imbalanced supply and demand cycles, compressed air energy storage (CAES) is a proven technology in grid-scale applications. This paper reviews the current state of micro scale CAES technology and describes a micro-scale advanced adiabatic CAES (A-CAES) system, where heat generated during compression is stored for use in the discharge phase. It will also describe a thermodynamic model, developed in EES (Engineering Equation Solver) to evaluate the performance and critical parameters of the discharge phase of the proposed system. Three configurations are explained including: single turbine without preheater, two turbines with preheaters, and three turbines with preheaters. It is shown that the micro-scale A-CAES is highly dependent upon key parameters including; regulator pressure, air pressure and volume, thermal energy storage temperature and flow rate and the number of turbines. It was found that a micro-scale AA-CAES, when optimized with an appropriate configuration, could deliver energy input to output efficiency of up to 70%.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=CAES" title="CAES">CAES</a>, <a href="https://publications.waset.org/search?q=adiabatic%20compressed%20air%20energy%20storage" title=" adiabatic compressed air energy storage"> adiabatic compressed air energy storage</a>, <a href="https://publications.waset.org/search?q=expansion%20phase" title=" expansion phase"> expansion phase</a>, <a href="https://publications.waset.org/search?q=micro%20generation" title=" micro generation"> micro generation</a>, <a href="https://publications.waset.org/search?q=thermodynamic." title=" thermodynamic."> thermodynamic.</a> </p> <a href="https://publications.waset.org/10008304/energy-efficiency-analysis-of-discharge-modes-of-an-adiabatic-compressed-air-energy-storage-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10008304/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10008304/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10008304/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10008304/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10008304/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10008304/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10008304/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10008304/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10008304/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10008304/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10008304.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1117</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Sampling of Variables in Discrete-Event Simulation using the Example of Inventory Evolutions in Job-Shop-Systems Based on Deterministic and Non-Deterministic Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Bernd%20Scholz-Reiter">Bernd Scholz-Reiter</a>, <a href="https://publications.waset.org/search?q=Christian%20Toonen"> Christian Toonen</a>, <a href="https://publications.waset.org/search?q=Jan%20Topi%20Tervo"> Jan Topi Tervo</a>, <a href="https://publications.waset.org/search?q=Dennis%20Lappe"> Dennis Lappe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Time series analysis often requires data that represents the evolution of an observed variable in equidistant time steps. In order to collect this data sampling is applied. While continuous signals may be sampled, analyzed and reconstructed applying Shannon-s sampling theorem, time-discrete signals have to be dealt with differently. In this article we consider the discrete-event simulation (DES) of job-shop-systems and study the effects of different sampling rates on data quality regarding completeness and accuracy of reconstructed inventory evolutions. At this we discuss deterministic as well as non-deterministic behavior of system variables.

These words show the beliefs and views of the earliest people about their structure. It is also necessary to search for the vocabulary in the Indo-European and Indo-Iranian periods. During recent centuries, comparative linguistics and mythology have facilitated the common Indo-European lexicon to reconstruct. The Persians have been appeared in the Assyrian inscriptions and affected by the Mesopotamians. It is also worth paying attention to the cultural and linguistic exchanges with the Mesopotamian civilizations. This paper aims to show the morphology of Pārsa based on linguistic evolutions and historical-mythological traditions. The method of this study is also to reconstruct both morphology and the earliest form of Persia. Then, it is tried to find the most plausive meaning according to the historical-mythological traditions.

Modeling of two phase flow, particularly liquid – vapor flow under diabatic conditions inside a horizontal tube using CFD analysis is difficult with the available two phase models in FLUENT due to continuously changing flow patterns. In the present analysis, CFD analysis of two phase flow of refrigerants inside a horizontal tube of inner diameter, 0.0085 m and 1.2 m length is carried out using homogeneous model under adiabatic conditions. The refrigerants considered are R22, R134a and R407C. The analysis is performed at different saturation temperatures and at different flow rates to evaluate the local frictional pressure drop. Using Homogeneous model, average properties are obtained for each of the refrigerants that is considered as single phase pseudo fluid. The so obtained pressure drop data is compared with the separated flow models available in literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Adiabatic%20conditions" title="Adiabatic conditions">Adiabatic conditions</a>, <a href="https://publications.waset.org/search?q=CFD%20analysis" title=" CFD analysis"> CFD analysis</a>, <a href="https://publications.waset.org/search?q=Homogeneousmodel%20and%20Liquid%20%E2%80%93%20Vapor%20flow." title=" Homogeneousmodel and Liquid – Vapor flow."> Homogeneousmodel and Liquid – Vapor flow.</a> </p> <a href="https://publications.waset.org/7320/cfd-analysis-of-two-phase-flow-in-a-horizontal-pipe-prediction-of-pressure-drop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7320/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7320/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7320/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7320/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7320/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7320/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7320/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7320/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7320/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7320/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7320.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3697</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Assessment of Modern RANS Models for the C3X Vane Film Cooling Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Mikhail%20Gritskevich">Mikhail Gritskevich</a>, <a href="https://publications.waset.org/search?q=Sebastian%20Hohenstein"> Sebastian Hohenstein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The paper presents the results of a detailed assessment of several modern Reynolds Averaged Navier-Stokes (RANS) turbulence models for prediction of C3X vane film cooling at various injection regimes. Three models are considered, namely the Shear Stress Transport (SST) model, the modification of the SST model accounting for the streamlines curvature (SST-CC), and the Explicit Algebraic Reynolds Stress Model (EARSM). It is shown that all the considered models face with a problem in prediction of the adiabatic effectiveness in the vicinity of the cooling holes; however, accounting for the Reynolds stress anisotropy within the EARSM model noticeably increases the solution accuracy. On the other hand, further downstream all the models provide a reasonable agreement with the experimental data for the adiabatic effectiveness and among the considered models the most accurate results are obtained with the use EARMS.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Discrete%20holes%20film%20cooling" title="Discrete holes film cooling">Discrete holes film cooling</a>, <a href="https://publications.waset.org/search?q=Reynolds%20Averaged%20Navier-Stokes" title=" Reynolds Averaged Navier-Stokes"> Reynolds Averaged Navier-Stokes</a>, <a href="https://publications.waset.org/search?q=Reynolds%20stress%20tensor%20anisotropy" title=" Reynolds stress tensor anisotropy"> Reynolds stress tensor anisotropy</a>, <a href="https://publications.waset.org/search?q=turbulent%20heat%20transfer." title=" turbulent heat transfer."> turbulent heat transfer.</a> </p> <a href="https://publications.waset.org/10007182/assessment-of-modern-rans-models-for-the-c3x-vane-film-cooling-prediction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10007182/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10007182/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10007182/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10007182/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10007182/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10007182/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10007182/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10007182/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10007182/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10007182/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10007182.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1122</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> Impact Deformation and Fracture Behaviour of Cobalt-Based Haynes 188 Superalloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Woei-Shyan%20Lee">Woei-Shyan Lee</a>, <a href="https://publications.waset.org/search?q=Hao-Chien%20Kao"> Hao-Chien Kao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The impact deformation and fracture behaviour of cobalt-based Haynes 188 superalloy are investigated by means of a split Hopkinson pressure bar. Impact tests are performed at strain rates ranging from 1&times;103 s-1 to 5&times;103 s-1 and temperatures between 25&deg;C and 800&deg;C. The experimental results indicate that the flow response and fracture characteristics of cobalt-based Haynes 188 superalloy are significantly dependent on the strain rate and temperature. The flow stress, work hardening rate and strain rate sensitivity all increase with increasing strain rate or decreasing temperature. It is shown that the impact response of the Haynes 188 specimens is adequately described by the Zerilli-Armstrong fcc model. The fracture analysis results indicate that the Haynes 188 specimens fail predominantly as the result of intensive localised shearing. Furthermore, it is shown that the flow localisation effect leads to the formation of adiabatic shear bands. The fracture surfaces of the deformed Haynes 188 specimens are characterised by dimple- and / or cleavage-like structure with knobby features. The knobby features are thought to be the result of a rise in the local temperature to a value greater than the melting point.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Haynes%20188%20alloy" title="Haynes 188 alloy">Haynes 188 alloy</a>, <a href="https://publications.waset.org/search?q=impact" title=" impact"> impact</a>, <a href="https://publications.waset.org/search?q=strain%20rate%20and%20temperature%20effect" title=" strain rate and temperature effect"> strain rate and temperature effect</a>, <a href="https://publications.waset.org/search?q=adiabatic%20shearing." title=" adiabatic shearing.

Owing to the relatively high volume of the cementitious material present, the foundations tend to suffer thermal strains and internal cracking due to high temperatures and temperature gradients depending on factors such as geometry, mix design and level of restraint. This is a result of a fully coupled mechanism commonly known as THMC (Thermo- Hygro - Mechanical - Chemical) coupling whose kinetics peak during the early age of concrete. The focus of this paper is therefore to present and offer a discussion on the temperature and humidity evolutions occurring in mass pours such as wind turbine gravity foundations based on sensor results obtained from the monitoring of an actual wind turbine foundation. To offer prediction of the evolutions, the formulation of a 3D Thermal-Hydro-Chemical (THC) model that is mainly derived from classical fundamental physical laws is also presented and discussed. The THC model can be mathematically fully coupled in Finite Element analyses. In the current study, COMSOL Multi-physics software was used to simulate the 3D THC coupling that occurred in the monitored wind turbine foundation to predict the temperature evolution at five different points within the foundation from time of casting.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Early%20age%20behavior" title="Early age behavior">Early age behavior</a>, <a href="https://publications.waset.org/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a>, <a href="https://publications.waset.org/search?q=THC%203D%20models" title=" THC 3D models"> THC 3D models</a>, <a href="https://publications.waset.org/search?q=wind%20turbines." title=" wind turbines."> wind turbines.</a> </p> <a href="https://publications.waset.org/10012423/early-age-behavior-of-wind-turbine-gravity-foundations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10012423/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10012423/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10012423/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10012423/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10012423/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10012423/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10012423/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10012423/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10012423/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10012423/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10012423.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Correlation to Predict Thermal Performance According to Working Fluids of Vertical Closed-Loop Pulsating Heat Pipe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Niti%20Kammuang-lue">Niti Kammuang-lue</a>, <a href="https://publications.waset.org/search?q=Kritsada%20On-ai"> Kritsada On-ai</a>, <a href="https://publications.waset.org/search?q=Phrut%20Sakulchangsatjatai"> Phrut Sakulchangsatjatai</a>, <a href="https://publications.waset.org/search?q=Pradit%20Terdtoon"> Pradit Terdtoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The objectives of this paper are to investigate effects of dimensionless numbers on thermal performance of the vertical closed-loop pulsating heat pipe (VCLPHP) and to establish a correlation to predict the thermal performance of the VCLPHP. The CLPHPs were made of long copper capillary tubes with inner diameters of 1.50, 1.78, and 2.16mm and bent into 26 turns. Then, both ends were connected together to form a loop. The evaporator, adiabatic, and condenser sections length were equal to 50 and 150 mm. R123, R141b, acetone, ethanol, and water were chosen as variable working fluids with constant filling ratio of 50% by total volume. Inlet temperature of heating medium and adiabatic section temperature was constantly controlled at 80 and 50<sup>o</sup>C, respectively. Thermal performance was represented in a term of Kutateladze number (<em>Ku</em>). It can be concluded that when Prandtl number of liquid working fluid (<em>Pr<sub>l</sub></em>), and Karman number (<em>Ka</em>) increases, thermal performance increases. On contrary, when Bond number (<em>Bo</em>), Jacob number (<em>Ja</em>), and Aspect ratio (<em>L<sub>e</sub>/D<sub>i</sub></em>) increases, thermal performance decreases. Moreover, the correlation to predict more precise thermal performance has been successfully established by analyzing on all dimensionless numbers that have effect on the thermal performance of the VCLPHP.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Vertical%20closed-loop%20pulsating%20heat%20pipe" title="Vertical closed-loop pulsating heat pipe">Vertical closed-loop pulsating heat pipe</a>, <a href="https://publications.waset.org/search?q=working%20fluid" title=" working fluid"> working fluid</a>, <a href="https://publications.waset.org/search?q=thermal%20performance" title=" thermal performance"> thermal performance</a>, <a href="https://publications.waset.org/search?q=dimensionless%20parameter." title=" dimensionless parameter."> dimensionless parameter.</a> </p> <a href="https://publications.waset.org/9998291/correlation-to-predict-thermal-performance-according-to-working-fluids-of-vertical-closed-loop-pulsating-heat-pipe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9998291/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9998291/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9998291/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9998291/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9998291/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9998291/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9998291/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9998291/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9998291/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9998291/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9998291.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2336</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">61</span> An Approximation Method for Three Quark Systems in the Hyper-Spherical Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=B.%20Rezaei">B.

This modification creates a novel fictitious force leading to a spontaneous exchange symmetry breaking at high double excitation. The Pauli principle must therefore be regarded as approximation valid only at low excitation energy. Threshold electron scattering from high Rydberg states shows an unexpected time reversal symmetry breaking.

Samples of CEM II mortar were prepared and subjected to accelerated carbonation at 20°C, 65% relative humidity and 20% CO2 concentration. We examined the evolutions of the gas permeability, the thermal conductivity, the thermal diffusivity, the volume of the solid phase by helium pycnometry, the longitudinal and transverse ultrasonic velocities. The principal contribution of this work is that, apart of the gas permeability, changes in other non destructive properties have never been studied during the carbonation of cement materials. These properties are important in predicting/measuring the durability of reinforced concrete in CO2 environment. The carbonation depth and the porosity accessible to water were also reported in order to explain comprehensively the changes in non destructive parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Carbonation" title="Carbonation">Carbonation</a>, <a href="https://publications.waset.org/search?q=cement%20mortar" title=" cement mortar"> cement mortar</a>, <a href="https://publications.waset.org/search?q=longitudinal%20and%20transverse%20ultrasonic%20velocities" title=" longitudinal and transverse ultrasonic velocities"> longitudinal and transverse ultrasonic velocities</a>, <a href="https://publications.waset.org/search?q=non%20destructive%20tests." title=" non destructive tests."> non destructive tests.</a> </p> <a href="https://publications.waset.org/3255/non-destructive-characterisation-of-cement-mortar-during-carbonation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/3255/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/3255/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/3255/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/3255/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/3255/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/3255/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/3255/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/3255/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/3255/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/3255/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/3255.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1750</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Numerical Evaluation of Turbulent Friction on Walls in the Penstock of the Trois-Gorges Dam by the Swamee-Jain Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=T.%20Tchawe%20Moukam">T.

In this work, this equation was applied to the penstock of the Three Gorges dam in order to observe the evolution of the turbulent boundary layer and the friction along the walls. Thus, the study is being carried out using a 3D digital approach in FLUENT in order to take into account the wall effects. It appears that according to the position of the portions, we have a variation in the evolutions of the turbulent friction and of the values of the boundary layer. We also observe that the inclination of the pipe has a significant influence on this turbulent friction; similarly, one could not make a fair evaluation of the latter without specifying the choice and location of the wall.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Hydroelectric%20dam" title="Hydroelectric dam">Hydroelectric dam</a>, <a href="https://publications.waset.org/search?q=penstock" title=" penstock"> penstock</a>, <a href="https://publications.waset.org/search?q=turbulent%20friction" title=" turbulent friction"> turbulent friction</a>, <a href="https://publications.waset.org/search?q=boundary%20layer" title=" boundary layer"> boundary layer</a>, <a href="https://publications.waset.org/search?q=CFD." title=" CFD."> CFD.</a> </p> <a href="https://publications.waset.org/10012586/numerical-evaluation-of-turbulent-friction-on-walls-in-the-penstock-of-the-trois-gorges-dam-by-the-swamee-jain-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10012586/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10012586/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10012586/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10012586/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10012586/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10012586/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10012586/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10012586/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10012586/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10012586/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10012586.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">470</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Phenomenological and Theoretical Analysis of Relativistic Temperature Transformation and Relativistic Entropy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Marko%20Popovic">Marko Popovic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are three possible effects of Special Theory of Relativity (STR) on a thermodynamic system. Planck and Einstein looked upon this process as isobaric; on the other hand Ott saw it as an adiabatic process. However plenty of logical reasons show that the process is isotherm. Our phenomenological consideration demonstrates that the temperature is invariant with Lorenz transformation. In that case process is isotherm, so volume and pressure are Lorentz covariant. If the process is isotherm the Boyles law is Lorentz invariant. Also equilibrium constant and Gibbs energy, activation energy, enthalpy entropy and extent of the reaction became Lorentz invariant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=STR" title="STR">STR</a>, <a href="https://publications.waset.org/search?q=relativistic%20temperature%20transformation" title=" relativistic temperature transformation"> relativistic temperature transformation</a>, <a href="https://publications.waset.org/search?q=Boyle%27slaw" title=" Boyle&#039;slaw"> Boyle&#039;slaw</a>, <a href="https://publications.waset.org/search?q=equilibrium%20constant" title=" equilibrium constant"> equilibrium constant</a>, <a href="https://publications.waset.org/search?q=Gibbs%20energy." title=" Gibbs energy."> Gibbs energy.</a> </p> <a href="https://publications.waset.org/13452/phenomenological-and-theoretical-analysis-of-relativistic-temperature-transformation-and-relativistic-entropy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13452/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13452/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13452/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13452/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13452/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13452/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13452/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13452/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13452/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13452/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13452.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2291</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Simulation of the Temperature and Heat Gain by Solar Parabolic Trough Collector in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=M.%20Ouagued">M.

The study is based on a mathematical modeling of the PTC. Heat balance has been established respectively on the heat transfer fluid (HTF), the absorber tube and the glass envelop using the principle of energy conservation at each surface of the HCE cross-sectionn. The modified Euler method is used to solve the obtained differential equations. At first the results for typical days of two seasons the thermal behavior of the HTF, the absorber and the envelope are obtained. Then to determine the thermal performances of the heat transfer fluid, different oils are considered and their temperature and heat gain evolutions compared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Direct%20solar%20irradiance" title="Direct solar irradiance">Direct solar irradiance</a>, <a href="https://publications.waset.org/search?q=solar%20radiation%20in%20Algeria" title=" solar radiation in Algeria"> solar radiation in Algeria</a>, <a href="https://publications.waset.org/search?q=solar%20parabolic%20trough%20collector" title=" solar parabolic trough collector"> solar parabolic trough collector</a>, <a href="https://publications.waset.org/search?q=heat%20balance" title=" heat balance"> heat balance</a>, <a href="https://publications.waset.org/search?q=thermal%20oil%0Aperformance" title=" thermal oil performance"> thermal oil performance</a> </p> <a href="https://publications.waset.org/6654/simulation-of-the-temperature-and-heat-gain-by-solar-parabolic-trough-collector-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/6654/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/6654/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/6654/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/6654/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/6654/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/6654/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/6654/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/6654/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/6654/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/6654/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/6654.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3652</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Effects of Carbonation on the Microstructure and Macro Physical Properties of Cement Mortar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Son%20Tung%20Pham">Son Tung Pham</a>, <a href="https://publications.waset.org/search?q=William%20Prince"> William Prince</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work was to examine the changes in the microstructure and macro physical properties caused by the carbonation of normalised CEM II mortar. Samples were prepared and subjected to accelerated carbonation at 20°C, 65% relative humidity and 20% CO2 concentration. On the microstructure scale, the evolutions of the cumulative pore volume, pore size distribution, and specific surface area during carbonation were calculated from the adsorption desorption isotherms of nitrogen. We also examined the evolution of macro physical properties such as the porosity accessible to water, the gas permeability, and thermal conductivity. The conflict between the results of nitrogen porosity and water porosity indicated that the porous domains explored using these two techniques are different and help to complementarily evaluate the effects of carbonation. This is a multi-scale study where results on microstructural changes can help to explain the evolution of macro physical properties. <p class="card-text"><strong>Keywords:</strong> <a
