NUMERICAL SIMULATION OF EFFECTS OF A NON-IONIZED FLUID INJECTION AND SUCTION ON THE MHD FLOW IN A CIRCULAR CHANNEL

摘要: Control of a fluid flow velocity profile by injection and suction non-ionized in presence uniform steady magnetic field has important technical applications. In this paper, the unsteady incompressible viscous conducting been investigated circular channel. The channel walls are assumed to be non-conducting porous. They subjected which is perpendicular axis channel, then applied at walls. well known equations Magnetohydrodynamics governed motion an electrically that field. numerical solution carried out finite difference approach. results present simulation shown through wall can controlled effectively, main especially industrial purposes. obtained for different values injected sucked rate effect Hartman number on investigated. Finally, good agreement seen between presented corresponding data element method.
