20.500.12556/RUL-145161 Effect of the curvature angle in a conduit with an adiabatic cylinder over a backward facing step on the magnetohydrodynamic behaviour in the presence of a nanofluid Vpliv kota ukrivljenosti v kanalu z adiabatnim valjem nad nazaj obrnjeno stopnico na magnetohidrodinamično obnašanje ob prisotnosti nanofluida A backward facing duct are present in various industrial applications especially those focused on heat transfer. The flow through a curved backward facing duct especially in the presence of nanofluid presents complexities compared to a straight backward facing step (BFS) duct. Therefore, the present numerical study deals a nanofluid flow (Fe3O4-H2O) forced convection in a curved backward facing duct. The objective of this investigation is to visualize at different curvature angles g (0°, 30°, 45°, 60°, 90°) imposed on the top wall of the duct, the effect of Hartmann number Ha (0, 50, 100), magnetic field inclination angle γ (0°, 60°, 90°), Reynolds number Re (10, 100, 200) and nanoparticle volume fraction φ (0 %, 0.05 %, 0.1 %). The dimensionless governing equations are solved using the multigrid finite element method. The results showed that the heat transfer was enhanced at the curved angle g = 90° for large Hartman numbers, thus, the average Nusselt number increased with a ratio of 240.74 % in the case of Hartmann number (Ha = 100). forced convection backward-facing step curved conduit fixed cylinder ferrofluid finite element method magnetohydrodynamic prisilna konvekcija nazaj obrnjen korak ukrivljen kanal nepremični valj ferrofluid metoda končnih elementov magnetohidrodinamika true false true Angleški jezik Slovenski jezik Članek v reviji 2023-04-11 14:10:18 2023-04-11 14:10:22 2023-04-12 03:32:49 0000-00-00 00:00:00 2023 0 0 Str. 135-154 no. 3/4 Vol. 69 Mar./Apr. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.62 0039-2480 10.5545/sv-jme.2022.239 148427267 Derbal...-Effect_of_the_Curvature_Angle_in_a_Conduit....pdf Derbal...-Effect_of_the_Curvature_Angle_in_a_Conduit....pdf 1 CDBA31F15590B8C9E7B3A7F1B54B26D8 6b7ca4305a2a637b236417bf67857d9a721a7d66ca1980c74b9a940df189c6fc dd9bbca7-d861-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167845 https://www.sv-jme.eu/sl/article/effect-of-the-curvature-angle-in-a-conduit-with-an-adiabatic-cylinder-over-a-bfs-on-the-mhd-behaviour-in-the-presence-of-a-nanofluid/ 1 b324140f-d861-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167844 Fakulteta za strojništvo Strojniški vestnik 0 0 0
