In order to consider uncertainty in engineering problem, the optimization problem should be solved for a suitable range of the each uncertain input variable instead of just one estimated point. Using deterministic optimization problem, a large computational burden is required to consider every possible and probable combination of uncertain input variables. Several methods have been reported in the literature to deal with problems under uncertainty.

The Field Operation And Manipulation (OpenFOAM) platform is used as the computational Fluid Dynamics (CFD) tool. Firstly, the influences of grid resolution on the results of k-ε, k-ω, and LES turbulence models are investigated and compared with those of experimental measurements. A numerical pressure under-shoot is appeared near the end of blade pressure surface which is sensitive to grid resolution and flow turbulence modeling. The LES model is able to resolve separation on a coarse and fine grid resolutions. Secondly, the off-design flow condition is modeled by negative and positive inflow incidence angles. The numerical experiments show that a separation bubble generated on blade pressure side is predicted by LES. The total pressure drop is also been calculated at incidence angle between -20◦ and +8◦. The minimum total pressure drop is obtained by k-ω and LES at the design point. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20pressure%20turbine" title="low pressure turbine">low pressure turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=off-design%20performance" title=" off-design performance"> off-design performance</a>, <a href="https://publications.waset.org/abstracts/search?q=openFOAM" title=" openFOAM"> openFOAM</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulence%20modeling" title=" turbulence modeling"> turbulence modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20separation" title=" flow separation"> flow separation</a> </p> <a href="https://publications.waset.org/abstracts/26688/numerical-study-of-off-design-performance-of-a-highly-loaded-low-pressure-turbine-cascade" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26688.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">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">264</span> Computational Fluid Dynamic Modeling of Mixing Enhancement by Stimulation of Ferrofluid under Magnetic Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Azimi">Neda Azimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Rahimi"> Masoud Rahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Faezeh%20Mohammadi"> Faezeh Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational fluid dynamics (CFD) simulation was performed to investigate the effect of ferrofluid stimulation on hydrodynamic and mass transfer characteristics of two immiscible liquid phases in a Y-micromixer. The main purpose of this work was to develop a numerical model that is able to simulate hydrodynamic of the ferrofluid flow under magnetic field and determine its effect on mass transfer characteristics. A uniform external magnetic field was applied perpendicular to the flow direction. The volume of fluid (VOF) approach was used for simulating the multiphase flow of ferrofluid and two-immiscible liquid flows. The geometric reconstruction scheme (Geo-Reconstruct) based on piecewise linear interpolation (PLIC) was used for reconstruction of the interface in the VOF approach. The mass transfer rate was defined via an equation as a function of mass concentration gradient of the transported species and added into the phase interaction panel using the user-defined function (UDF). The magnetic field was solved numerically by Fluent MHD module based on solving the magnetic induction equation method. CFD results were validated by experimental data and good agreements have been achieved, which maximum relative error for extraction efficiency was about 7.52 %. It was showed that ferrofluid actuation by a magnetic field can be considered as an efficient mixing agent for liquid-liquid two-phase mass transfer in microdevices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD%20modeling" title="CFD modeling">CFD modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic" title=" hydrodynamic"> hydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=micromixer" title=" micromixer"> micromixer</a>, <a href="https://publications.waset.org/abstracts/search?q=ferrofluid" title=" ferrofluid"> ferrofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=mixing" title=" mixing"> mixing</a> </p> <a href="https://publications.waset.org/abstracts/102582/computational-fluid-dynamic-modeling-of-mixing-enhancement-by-stimulation-of-ferrofluid-under-magnetic-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102582.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">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">263</span> Development of an Implicit Physical Influence Upwind Scheme for Cell-Centered Finite Volume Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shidvash%20Vakilipour">Shidvash Vakilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Mohammadi"> Masoud Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rouzbeh%20Riazi"> Rouzbeh Riazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Scott%20Ormiston"> Scott Ormiston</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimia%20Amiri"> Kimia Amiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Barati"> Sahar Barati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An essential component of a finite volume method (FVM) is the advection scheme that estimates values on the cell faces based on the calculated values on the nodes or cell centers. The most widely used advection schemes are upwind schemes. These schemes have been developed in FVM on different kinds of structured and unstructured grids. In this research, the physical influence scheme (PIS) is developed for a cell-centered FVM that uses an implicit coupled solver. Results are compared with the exponential differencing scheme (EDS) and the skew upwind differencing scheme (SUDS). Accuracy of these schemes is evaluated for a lid-driven cavity flow at Re = 1000, 3200, and 5000 and a backward-facing step flow at Re = 800. Simulations show considerable differences between the results of EDS scheme with benchmarks, especially for the lid-driven cavity flow at high Reynolds numbers. These differences occur due to false diffusion. Comparing SUDS and PIS schemes shows relatively close results for the backward-facing step flow and different results in lid-driven cavity flow. The poor results of SUDS in the lid-driven cavity flow can be related to its lack of sensitivity to the pressure difference between cell face and upwind points, which is critical for the prediction of such vortex dominant flows. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell-centered%20finite%20volume%20method" title="cell-centered finite volume method">cell-centered finite volume method</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20solver" title=" coupled solver"> coupled solver</a>, <a href="https://publications.waset.org/abstracts/search?q=exponential%20differencing%20scheme%20%28EDS%29" title=" exponential differencing scheme (EDS)"> exponential differencing scheme (EDS)</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20influence%20scheme%20%28PIS%29" title=" physical influence scheme (PIS)"> physical influence scheme (PIS)</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20weighted%20interpolation%20method%20%28PWIM%29" title=" pressure weighted interpolation method (PWIM)"> pressure weighted interpolation method (PWIM)</a>, <a href="https://publications.waset.org/abstracts/search?q=skew%20upwind%20differencing%20scheme%20%28SUDS%29" title=" skew upwind differencing scheme (SUDS)"> skew upwind differencing scheme (SUDS)</a> </p> <a href="https://publications.waset.org/abstracts/65764/development-of-an-implicit-physical-influence-upwind-scheme-for-cell-centered-finite-volume-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65764.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">284</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">262</span> A Two-Phase Flow Interface Tracking Algorithm Using a Fully Coupled Pressure-Based Finite Volume Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shidvash%20Vakilipour">Shidvash Vakilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Scott%20Ormiston"> Scott Ormiston</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Mohammadi"> Masoud Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rouzbeh%20Riazi"> Rouzbeh Riazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimia%20Amiri"> Kimia Amiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Barati"> Sahar Barati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two-phase and multi-phase flows are common flow types in fluid mechanics engineering. Among the basic and applied problems of these flow types, two-phase parallel flow is the one that two immiscible fluids flow in the vicinity of each other. In this type of flow, fluid properties (e.g. density, viscosity, and temperature) are different at the two sides of the interface of the two fluids. The most challenging part of the numerical simulation of two-phase flow is to determine the location of interface accurately. In the present work, a coupled interface tracking algorithm is developed based on Arbitrary Lagrangian-Eulerian (ALE) approach using a cell-centered, pressure-based, coupled solver. To validate this algorithm, an analytical solution for fully developed two-phase flow in presence of gravity is derived, and then, the results of the numerical simulation of this flow are compared with analytical solution at various flow conditions. The results of the simulations show good accuracy of the algorithm despite using a nearly coarse and uniform grid. Temporal variations of interface profile toward the steady-state solution show that a greater difference between fluids properties (especially dynamic viscosity) will result in larger traveling waves. Gravity effect studies also show that favorable gravity will result in a reduction of heavier fluid thickness and adverse gravity leads to increasing it with respect to the zero gravity condition.

One kind of these mechanisms is 3-<u>R</u>RR which is a parallel mechanism and has three revolute joints. This paper aims to robust control a 3-<u>R</u>RR planner mechanism and it presents that this could be used for other mechanisms. So, a significant problem in mechanisms control could be solved.

Tolkien's literary works in general and on Middle-Earth in particular. Moreover, despite the fact that mythology is usually regarded as a thing of the past predominantly found in the early works of literature, this inquiry reveals that how modern literary works can artistically benefit from mythological elements of Old English Era so as to enrich their content and stand out as innovative masterpieces. Indeed, having been a philologist and well-acquainted with mythological literature, Tolkien paved the way for a novel understanding of literature by bridging the gap between the old and the new. In the end, it was concluded that had mythology not been utilised by Tolkien, his works, and on top of all, Middle-Earth, would not have turned into a modern literary showpiece. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=literature" title="literature">literature</a>, <a href="https://publications.waset.org/abstracts/search?q=Middle-Earth" title=" Middle-Earth"> Middle-Earth</a>, <a href="https://publications.waset.org/abstracts/search?q=mythology" title=" mythology"> mythology</a>, <a href="https://publications.waset.org/abstracts/search?q=Tolkien" title=" Tolkien "> Tolkien </a> </p> <a href="https://publications.waset.org/abstracts/131604/mythological-influences-on-the-works-of-j-r-r-tolkien-a-scrutiny-of-middle-earth-stories" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131604.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">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">246</span> Synthesis and Biological Activity Evaluation of U Complexes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Kazem%20Mohammadi">Mohammad Kazem Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of anticancer agents forms an important part of the treatment of cancer of various types.

One of the problems caused the reduction of pistachio proceeds is related to biennial- bearing or alternative bearing. Biennial- bearing is very important and is happened because of the fallen female bloom buds in vintage year. This test was done according to random blocks of 6 orchards in the type of Ahmad Aghaie with 4 iterations. Vegetative properties of branch are investigated. The results are shown that if the bunch numbers are increased, the possibility of falling is increased in bloom buds. The least possibility of falling of bloom buds is specified in trimming of one bunch and has significant difference with other trimming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternate%20bearing" title="alternate bearing">alternate bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=pistachio" title=" pistachio"> pistachio</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster" title=" cluster"> cluster</a>, <a href="https://publications.waset.org/abstracts/search?q=bud" title=" bud"> bud</a> </p> <a href="https://publications.waset.org/abstracts/39450/the-effect-of-bunch-in-the-branch-on-vegetative-characteristics-of-pistacia-vera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39450.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">437</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">243</span> Joining of Aluminum and Steel in Car Body Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mahdi%20Mohammadi">Mohammad Mahdi Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Zinc-coated steel sheets have been joined with aluminum samples in an overlapping as well as in a butt-joint configuration.

The costs can be generally divided into four parts: the materials used, the equipment used, the manpower required, and the time required. In this article, we are trying to talk about the three items of equipment, manpower, and time, and examine how the use of apps can reduce the cost of construction, while due to various reasons, it has received less attention in the field of app design. Also, because we intend to use these apps in construction and they are used by engineers and experts, we define these apps as engineering apps because the idea of their design must be by an engineer who works in that field. Also, considering that most engineers are familiar with programming during their studies, they can design the apps they need using simple programming software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=layout" title="layout">layout</a>, <a href="https://publications.waset.org/abstracts/search?q=as-bilt" title=" as-bilt"> as-bilt</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=maps" title=" maps"> maps</a> </p> <a href="https://publications.waset.org/abstracts/183643/apps-reduce-the-cost-of-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183643.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">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">238</span> Study the Effect of Friction on Barreling Behavior during Upsetting Process Using Anand Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Mohammadi%20Majd">H.

Furthermore, tribological conditions influence workpiece deformation and its dimensional precision. A viscoplastic constitutive law, the Anand model, was applied to represent the inelastic deformation behavior in upsetting process. This paper presents research results of the influence of contact friction coefficient on a workpiece deformation in upsetting process.finite element parameters. This technique was tested for three different specimens simulations of the upsetting and the corresponding material and can be successfully employed to predict the deformation of the upsetting process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction" title="friction">friction</a>, <a
