The Power law model was adopted in this study to empirically correlate fiction factor (f) and the percentage of drag reduction (%Dr) from experimental data for Reynolds number range (534-14695) and the concentration range from 3 to 12 wt.%.","owner":{"id":137054209,"first_name":"Ansam","middle_initials":"A D I L","last_name":"Mohammed","page_name":"adelansam","domain_name":"independent","created_at":"2019-11-27T04:58:21.116-08:00","display_name":"Ansam A D I L Mohammed","url":"https://independent.academia.edu/adelansam"},"attachments":[],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":2435,"name":"Fluid Mechanics","url":"https://www.academia.edu/Documents/in/Fluid_Mechanics"},{"id":10745,"name":"Clean Coal Technologies","url":"https://www.academia.edu/Documents/in/Clean_Coal_Technologies"},{"id":10875,"name":"Aerodynamics","url":"https://www.academia.edu/Documents/in/Aerodynamics"},{"id":21655,"name":"Aerodynamics Of Cars","url":"https://www.academia.edu/Documents/in/Aerodynamics_Of_Cars"},{"id":34478,"name":"Food Science and Technology","url":"https://www.academia.edu/Documents/in/Food_Science_and_Technology"},{"id":48636,"name":"Simulation","url":"https://www.academia.edu/Documents/in/Simulation"},{"id":127831,"name":"Coal Geology","url":"https://www.academia.edu/Documents/in/Coal_Geology"},{"id":146455,"name":"New Car Model Design","url":"https://www.academia.edu/Documents/in/New_Car_Model_Design"},{"id":171114,"name":"Turbulent Flow","url":"https://www.academia.edu/Documents/in/Turbulent_Flow"},{"id":191117,"name":"High Temperature","url":"https://www.academia.edu/Documents/in/High_Temperature"},{"id":246169,"name":"Strength of materials","url":"https://www.academia.edu/Documents/in/Strength_of_materials"},{"id":426828,"name":"Unconventional Energy","url":"https://www.academia.edu/Documents/in/Unconventional_Energy"},{"id":537231,"name":"Viscosity Models for heavy crude oil emulsion flow","url":"https://www.academia.edu/Documents/in/Viscosity_Models_for_heavy_crude_oil_emulsion_flow"},{"id":622183,"name":"Flow induced vibrations","url":"https://www.academia.edu/Documents/in/Flow_induced_vibrations"},{"id":688382,"name":"Mechanical Engginering","url":"https://www.academia.edu/Documents/in/Mechanical_Engginering"},{"id":867022,"name":"Boundary Condition","url":"https://www.academia.edu/Documents/in/Boundary_Condition"},{"id":1304404,"name":"Underground Coal Gasification","url":"https://www.academia.edu/Documents/in/Underground_Coal_Gasification"},{"id":1959453,"name":"Naphtha Catalytic Reforming","url":"https://www.academia.edu/Documents/in/Naphtha_Catalytic_Reforming"},{"id":3666724,"name":"external flow","url":"https://www.academia.edu/Documents/in/external_flow"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="105490442"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/105490442/Optimizing_the_size_for_Solar_Parabolic_Trough_Concentrator_numerically"><img alt="Research paper thumbnail of Optimizing the size for Solar Parabolic Trough Concentrator numerically" class="work-thumbnail" src="https://attachments.academia-assets.com/104930698/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/105490442/Optimizing_the_size_for_Solar_Parabolic_Trough_Concentrator_numerically">Optimizing the size for Solar Parabolic Trough Concentrator numerically</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">A numerical study of the performance of a concentrated solar parabolic trough is presented in thi...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">A numerical study of the performance of a concentrated solar parabolic trough is presented in this article.

The study covered two twisted tape ratios (Y=6 and 7.2), three Reynolds numbers (8000, 10000, and 13000), and three rotating velocities (0, 200, and 400) RPM. It is found that the twisted ratio (Y) and the rotating velocity of twisted tape have a significant effect on the thermal performance. The results illustrated that the usage of rotating twisted tape inserted in tube produces a higher heat transfer rate than that produced by the stationary twisted tape. Empirical correlations of Nusselt number, friction factor, and enhancement efficiency as a function of Reynolds number were deduced.

Decrease in mixing reduces the effect of process instability, regular mixing with mixing dividers has been shown to be useful for biogas production.","owner":{"id":137054209,"first_name":"Ansam","middle_initials":"A D I L","last_name":"Mohammed","page_name":"adelansam","domain_name":"independent","created_at":"2019-11-27T04:58:21.116-08:00","display_name":"Ansam A D I L Mohammed","url":"https://independent.academia.edu/adelansam"},"attachments":[{"id":104703791,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/104703791/thumbnails/1.jpg","file_name":"IJLEMR_66719.pdf","download_url":"https://www.academia.edu/attachments/104703791/download_file?st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Experimental_units_for_biogas_production.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/104703791/IJLEMR_66719-libre.pdf?1690991693=\u0026response-content-disposition=attachment%3B+filename%3DExperimental_units_for_biogas_production.pdf\u0026Expires=1734129491\u0026Signature=MiXwUJeLh68K0420B5CTg0PUotQyFUbTAGQ8Ou-ghgBMJ-jf1cp0JuqPuuTHvm02W-0sjI7EE8AFsy1hvc81QT3hpQSHLjVYmqeMui5foxXQU3ocIl5og4IzA6VBPxGLh1UKslN724-1wl6OpiCY1MkGzBnj-ClpGytOkNZYZ36z9xBWjmVZeXGcHDllPrnh81GZlxrbdIIGyxYcghKdbOGknHPN~GpscnM2UiwiGJ~M6WJ3MLS3rJCor-VeAwx65Uqrw9rMdGvt9qCxonp8U-gP~Zzhk~YQto1~f2zWyLz4j59Rb55BR5Ip8M11bLVUwQIBfESSir78M4mPCR5Qyg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":18186,"name":"Renewable energy resources","url":"https://www.academia.edu/Documents/in/Renewable_energy_resources"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="105179257"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/105179257/Numerical_Study_of_Convection_Air_Currents_Around_a_Hot_Cylinder_Inside_a_Triangular_Cavity"><img alt="Research paper thumbnail of Numerical Study of Convection Air Currents Around a Hot Cylinder Inside a Triangular Cavity" class="work-thumbnail" src="https://attachments.academia-assets.com/104703752/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/105179257/Numerical_Study_of_Convection_Air_Currents_Around_a_Hot_Cylinder_Inside_a_Triangular_Cavity">Numerical Study of Convection Air Currents Around a Hot Cylinder Inside a Triangular Cavity</a></div><div class="wp-workCard_item"><span>Al-Nahrain Journal for Engineering Sciences NJES</span><span>, 2023</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">A numerical study was performed of natural laminar convective heat transfer to its concentrated t...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">A numerical study was performed of natural laminar convective heat transfer to its concentrated triangular enclosure around a horizontal circular cylinder.

In general, the investigation of the structure of the systems affects the efficiency of the components that construct those systems. This review examined the influence of generated vibrations and internal pressure on fluid transport pipes using theoretical calculations, practical tests, and numerical analysis to identify and test the dynamic behavior of static fluid transport pipes. The experimental study considered the natural frequencies caused by the fluid pressure effect under various stability situations. The flow of all liquids, such as oil, water, gas, air, and vapors, through the pipes, was tested, and the mathematical models were correctly adjusted. All empirical, theoretical, numerical, and analytical research agrees that several approaches exist to develop, modify, and improve these metrics. However, one factor affecting rheological measurements is vibration, which was addressed as needed in the middle of the 20th century due to major discoveries that damage could be rooted in vibration.

That mean the Aluminium pipe better than copper pipe.","owner":{"id":137054209,"first_name":"Ansam","middle_initials":"A D I L","last_name":"Mohammed","page_name":"adelansam","domain_name":"independent","created_at":"2019-11-27T04:58:21.116-08:00","display_name":"Ansam A D I L Mohammed","url":"https://independent.academia.edu/adelansam"},"attachments":[{"id":104703557,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/104703557/thumbnails/1.jpg","file_name":"ARFMTSV106_N2_P177_193.pdf","download_url":"https://www.academia.edu/attachments/104703557/download_file?st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Journal_of_Advanced_Research_in_Fluid_Me.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/104703557/ARFMTSV106_N2_P177_193-libre.pdf?1690975289=\u0026response-content-disposition=attachment%3B+filename%3DJournal_of_Advanced_Research_in_Fluid_Me.pdf\u0026Expires=1734129491\u0026Signature=JlKvQ~e6w2195Y0fyWJUp7tIdSasUOUxegquvr09ZWbiXBOoYTv~d0uOS9xK1i5kQVI~5rXjgU5kF4gc68P~2Y6UljHIoQ1u0FYoEx-AZJdY433WsnfJ0sEclokI8Iuz1L0qx8lUmRcWa3xLPyahtLWN5myeOEpYMDDUdvDIEJSJU4HfoXoPwalF4wv8VHfzuN5q3PLyc8gNvI~4qJVHznvKRuRXy9I3mdnZHhT6WEzSJvfLA1QcpJS0oJ73JIbuJQih9CTMO6Sgo2Af6czPS9PAqxv52IIlTqGlKacjQY4ZR8phHfS9gBdAujv8uALowajifTzR~G0P0fAAqINORA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":622183,"name":"Flow induced vibrations","url":"https://www.academia.edu/Documents/in/Flow_induced_vibrations"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="105178905"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/105178905/Investigation_the_effect_of_various_vortex_generator_types_at_different_velocities_and_angles_of_attack_in_NACA_2412_Airfoil_on_lift_and_drag_coefficients"><img alt="Research paper thumbnail of Investigation the effect of various vortex generator types at different velocities and angles of attack in NACA 2412 Airfoil on lift and drag coefficients" class="work-thumbnail" src="https://attachments.academia-assets.com/104703461/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/105178905/Investigation_the_effect_of_various_vortex_generator_types_at_different_velocities_and_angles_of_attack_in_NACA_2412_Airfoil_on_lift_and_drag_coefficients">Investigation the effect of various vortex generator types at different velocities and angles of attack in NACA 2412 Airfoil on lift and drag coefficients</a></div><div class="wp-workCard_item"><span>International Journal of Latest Engineering and Management Research </span><span>, 2022</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Flow separation near the rear end of the aerodynamic body is the main cause of an increase in aer...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Flow separation near the rear end of the aerodynamic body is the main cause of an increase in aerodynamic drag and a decrease in aerodynamic lift, for that they put a device known as vortex generator (VG) to controlling the flow separation.

During the experiments, water was used as a heat transfer fluid. The twisted tape had been made of stainless steel and inserts screw-tape with a similar ratio of twisting, y=4. Cold and hot water streams meanwhile annulus and internal duct with square cross-sectional, respectively. The performance for the system with screwtape inserts is greater than that when the twisting tape had been used, also this performance in colder weather is improved when it was working in other conditions. Because tape inserts and impellers have a greater isothermal coefficient of kinetic friction than that of plain tubing by 7.6 and 13.2. Within the laminar region, experiments were carried out with success. Therefore, the mean Nusselt numbers for both twisted and screw tapes are significantly high than that for the ordinary duct over the whole laminar scope.

During the experiments, water was used as a heat transfer fluid. The twisted tape had been made of stainless steel and inserts screw-tape with a similar ratio of twisting, y=4. Cold and hot water streams meanwhile annulus and internal duct with square cross-sectional, respectively. The performance for the system with screwtape inserts is greater than that when the twisting tape had been used, also this performance in colder weather is improved when it was working in other conditions. Because tape inserts and impellers have a greater isothermal coefficient of kinetic friction than that of plain tubing by 7.6 and 13.2.

Results show that the thermal performance factors at constant pumping power in the case of tube fitted with PCR are higher than that in a tube fitted with TCR by 22%; and it improves as the angle of inclination moves from vertical to horizontal position by 3.25% for the case of PCR and vice versa for TCR case by 2.46%.","owner":{"id":137054209,"first_name":"Ansam","middle_initials":"A D I L","last_name":"Mohammed","page_name":"adelansam","domain_name":"independent","created_at":"2019-11-27T04:58:21.116-08:00","display_name":"Ansam A D I L Mohammed","url":"https://independent.academia.edu/adelansam"},"attachments":[{"id":104704193,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/104704193/thumbnails/1.jpg","file_name":"البحث.pdf","download_url":"https://www.academia.edu/attachments/104704193/download_file?st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Heat_transfer_Augmentation_in_an_Incline.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/104704193/%D8%A7%D9%84%D8%A8%D8%AD%D8%AB-libre.pdf?1690991627=\u0026response-content-disposition=attachment%3B+filename%3DHeat_transfer_Augmentation_in_an_Incline.pdf\u0026Expires=1734129491\u0026Signature=D3IRlXdRUdsDg2LlmpqRB2l2IR4hAJznmzD2jEqIZH2l8JofIyPMKDoUIGh-WnErdzl1WupS4Iuaf6Ppl3IFOUXXRCVaBMsr6lxq47m3WJ3PZeT~WmfU7tbcoAnv0F-ieLP-J-ln72kBuXzdxEmwpSSKvSj4rNrO1PzwjDBOz9rnMEParkjj9OofLu6CsfazTO2zyCFQgA7fy0-V1ZyXUnQajqZv57ePnmtMzrmuwdi5xW1vzWbUykSRjNahnQ6tPvstVSFXCuUY7~FboQ0iitPz7tDIe42TQVclRNcoctIP4IQqvyMJ-diR2mqKAa9V5lrqasL6T95ol8HqNxC6CA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":8067,"name":"Heat Transfer","url":"https://www.academia.edu/Documents/in/Heat_Transfer"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="105179674"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/105179674/Heat_Transfer_Augmentation_in_Tube_Fitted_with_Rotating_Twisted_Tape_Insert"><img alt="Research paper thumbnail of Heat Transfer Augmentation in Tube Fitted with Rotating Twisted Tape Insert" class="work-thumbnail" src="https://attachments.academia-assets.com/104704004/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/105179674/Heat_Transfer_Augmentation_in_Tube_Fitted_with_Rotating_Twisted_Tape_Insert">Heat Transfer Augmentation in Tube Fitted with Rotating Twisted Tape Insert</a></div><div class="wp-workCard_item"><span>Journal of Mechanical Engineering Research and Developments</span><span>, 2020</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Experimental investigation is carried out to study the forced convection heat transfer in a unifo...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Experimental investigation is carried out to study the forced convection heat transfer in a uniformly heated tube inserted with stationary and rotating twisted tape as a turbulator.

The Way biodegradable organisms are used to produce biogas using oxygen-free microorganisms. Anaerobic digestion is used to get rid of organic waste such as faces of animals and human waste, or to produce biogas. Improved processes are necessary to counter the evolution and expansion of the biogas industry and the growing demand for methane gas. This paper explores process techniques for the development of anaerobic digestion processes, including pre-treatment, studies on the effects of different mixing patterns, and assessments of water treatment techniques. Two pre-processors, mechanical and electrical, were assessed for the processing of radiation crop silage development, which is necessary to increase energy efficiency. Experimental results showed that the demand for mixing increased with organic loading. Excessive mixing, instability and shock loading during the start of the process increase concentrations of volatile fatty acids and inhibit the process. Decrease in mixing reduces the effect of process instability, regular mixing with mixing dividers has been shown to be useful for biogas production.","owner":{"id":137054209,"first_name":"Ansam","middle_initials":"A D I L","last_name":"Mohammed","page_name":"adelansam","domain_name":"independent","created_at":"2019-11-27T04:58:21.116-08:00","display_name":"Ansam A D I L Mohammed","url":"https://independent.academia.edu/adelansam"},"attachments":[{"id":104703791,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/104703791/thumbnails/1.jpg","file_name":"IJLEMR_66719.pdf","download_url":"https://www.academia.edu/attachments/104703791/download_file?st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Experimental_units_for_biogas_production.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/104703791/IJLEMR_66719-libre.pdf?1690991693=\u0026response-content-disposition=attachment%3B+filename%3DExperimental_units_for_biogas_production.pdf\u0026Expires=1734129491\u0026Signature=MiXwUJeLh68K0420B5CTg0PUotQyFUbTAGQ8Ou-ghgBMJ-jf1cp0JuqPuuTHvm02W-0sjI7EE8AFsy1hvc81QT3hpQSHLjVYmqeMui5foxXQU3ocIl5og4IzA6VBPxGLh1UKslN724-1wl6OpiCY1MkGzBnj-ClpGytOkNZYZ36z9xBWjmVZeXGcHDllPrnh81GZlxrbdIIGyxYcghKdbOGknHPN~GpscnM2UiwiGJ~M6WJ3MLS3rJCor-VeAwx65Uqrw9rMdGvt9qCxonp8U-gP~Zzhk~YQto1~f2zWyLz4j59Rb55BR5Ip8M11bLVUwQIBfESSir78M4mPCR5Qyg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":18186,"name":"Renewable energy resources","url":"https://www.academia.edu/Documents/in/Renewable_energy_resources"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="105179257"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/105179257/Numerical_Study_of_Convection_Air_Currents_Around_a_Hot_Cylinder_Inside_a_Triangular_Cavity"><img alt="Research paper thumbnail of Numerical Study of Convection Air Currents Around a Hot Cylinder Inside a Triangular Cavity" class="work-thumbnail" src="https://attachments.academia-assets.com/104703752/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/105179257/Numerical_Study_of_Convection_Air_Currents_Around_a_Hot_Cylinder_Inside_a_Triangular_Cavity">Numerical Study of Convection Air Currents Around a Hot Cylinder Inside a Triangular Cavity</a></div><div class="wp-workCard_item"><span>Al-Nahrain Journal for Engineering Sciences NJES</span><span>, 2023</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">A numerical study was performed of natural laminar convective heat transfer to its concentrated t...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">A numerical study was performed of natural laminar convective heat transfer to its concentrated triangular enclosure around a horizontal circular cylinder.

That mean the Aluminium pipe better than copper pipe.","owner":{"id":137054209,"first_name":"Ansam","middle_initials":"A D I L","last_name":"Mohammed","page_name":"adelansam","domain_name":"independent","created_at":"2019-11-27T04:58:21.116-08:00","display_name":"Ansam A D I L Mohammed","url":"https://independent.academia.edu/adelansam"},"attachments":[{"id":104703557,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/104703557/thumbnails/1.jpg","file_name":"ARFMTSV106_N2_P177_193.pdf","download_url":"https://www.academia.edu/attachments/104703557/download_file?st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Journal_of_Advanced_Research_in_Fluid_Me.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/104703557/ARFMTSV106_N2_P177_193-libre.pdf?1690975289=\u0026response-content-disposition=attachment%3B+filename%3DJournal_of_Advanced_Research_in_Fluid_Me.pdf\u0026Expires=1734129491\u0026Signature=JlKvQ~e6w2195Y0fyWJUp7tIdSasUOUxegquvr09ZWbiXBOoYTv~d0uOS9xK1i5kQVI~5rXjgU5kF4gc68P~2Y6UljHIoQ1u0FYoEx-AZJdY433WsnfJ0sEclokI8Iuz1L0qx8lUmRcWa3xLPyahtLWN5myeOEpYMDDUdvDIEJSJU4HfoXoPwalF4wv8VHfzuN5q3PLyc8gNvI~4qJVHznvKRuRXy9I3mdnZHhT6WEzSJvfLA1QcpJS0oJ73JIbuJQih9CTMO6Sgo2Af6czPS9PAqxv52IIlTqGlKacjQY4ZR8phHfS9gBdAujv8uALowajifTzR~G0P0fAAqINORA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":622183,"name":"Flow induced vibrations","url":"https://www.academia.edu/Documents/in/Flow_induced_vibrations"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="105178905"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/105178905/Investigation_the_effect_of_various_vortex_generator_types_at_different_velocities_and_angles_of_attack_in_NACA_2412_Airfoil_on_lift_and_drag_coefficients"><img alt="Research paper thumbnail of Investigation the effect of various vortex generator types at different velocities and angles of attack in NACA 2412 Airfoil on lift and drag coefficients" class="work-thumbnail" src="https://attachments.academia-assets.com/104703461/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/105178905/Investigation_the_effect_of_various_vortex_generator_types_at_different_velocities_and_angles_of_attack_in_NACA_2412_Airfoil_on_lift_and_drag_coefficients">Investigation the effect of various vortex generator types at different velocities and angles of attack in NACA 2412 Airfoil on lift and drag coefficients</a></div><div class="wp-workCard_item"><span>International Journal of Latest Engineering and Management Research </span><span>, 2022</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Flow separation near the rear end of the aerodynamic body is the main cause of an increase in aer...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Flow separation near the rear end of the aerodynamic body is the main cause of an increase in aerodynamic drag and a decrease in aerodynamic lift, for that they put a device known as vortex generator (VG) to controlling the flow separation.

During the experiments, water was used as a heat transfer fluid. The twisted tape had been made of stainless steel and inserts screw-tape with a similar ratio of twisting, y=4. Cold and hot water streams meanwhile annulus and internal duct with square cross-sectional, respectively. The performance for the system with screwtape inserts is greater than that when the twisting tape had been used, also this performance in colder weather is improved when it was working in other conditions. Because tape inserts and impellers have a greater isothermal coefficient of kinetic friction than that of plain tubing by 7.6 and 13.2. Within the laminar region, experiments were carried out with success. Therefore, the mean Nusselt numbers for both twisted and screw tapes are significantly high than that for the ordinary duct over the whole laminar scope. The screw twisted and tape inserts performance are 2.81 and 3.52 times larger than that for a duct's square plain at a constant power of pumping respectively.","owner":{"id":137054209,"first_name":"Ansam","middle_initials":"A D I L","last_name":"Mohammed","page_name":"adelansam","domain_name":"independent","created_at":"2019-11-27T04:58:21.116-08:00","display_name":"Ansam A D I L Mohammed","url":"https://independent.academia.edu/adelansam"},"attachments":[{"id":104703413,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/104703413/thumbnails/1.jpg","file_name":"IJME_Vol7.1_92.pdf","download_url":"https://www.academia.edu/attachments/104703413/download_file?st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&st=MTczNDEyNTg5MSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Investigation_of_the_thermal_performance.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/104703413/IJME_Vol7.1_92-libre.pdf?1690975345=\u0026response-content-disposition=attachment%3B+filename%3DInvestigation_of_the_thermal_performance.pdf\u0026Expires=1734129491\u0026Signature=GwIsLPepxmy-cMfR7fYSdHYUvHLeYt4qO4rCSkmk~Py3qExDOPQgE0OjeDeQkCesiR1XGjZDdg2aXWAqR5PyIdKvfs65XPjo5O7FKppSI~20T8uxiyxahX3sDt5l-if8hKQniGBlPK3v9vX8pImHUc-Lp-aQGXyk-D2E9U4Yv8St5EKPIajcE041P6QZN1GRJLQTVVixUVeWGyH9sO2d4rPPy-nMLtYxdKrph~nzT5-RiXcmpLeVlsQsZLmhOa~WetTyBDaQjsz1N7P5ygo3~I~UfdUJ-5tfJqBnldV2JyZ7u-SsvTlm9IzfuVTGKiGmhwyhl3pM9CyKg2LxLxqZ2Q__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":8067,"name":"Heat Transfer","url":"https://www.academia.edu/Documents/in/Heat_Transfer"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="105178700"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/105178700/Optimizing_the_size_for_Solar_Parabolic_Trough_Concentrator_numerically"><img alt="Research paper thumbnail of Optimizing the size for Solar Parabolic Trough Concentrator numerically" class="work-thumbnail" src="https://attachments.academia-assets.com/104703289/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/105178700/Optimizing_the_size_for_Solar_Parabolic_Trough_Concentrator_numerically">Optimizing the size for Solar Parabolic Trough Concentrator numerically</a></div><div class="wp-workCard_item"><span>International Journal of Mechanical Engineering</span><span>, 2022</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">A numerical study of the performance of a concentrated solar parabolic trough is presented in thi...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">A numerical study of the performance of a concentrated solar parabolic trough is presented in this article.
