عنوان انگلیسی NUMERICAL SIMULATION OF EFFECTS OF NON-IONIZED MASS INJECTION ON THE MHD FLOW IN A CIRCULAR CHANNEL
چکیده انگلیسی مقاله Control of a fluid velocity profile by injection and suction of non-ionized flow in presence of a uniform steady magnetic field has important technical applications. In this paper, the unsteady incompressible and viscous conducting fluid flow has been investigated in a circular channel. The channel wall has been assumed to be non-conducting and porous. It has been subjected to a uniform steady magnetic field which is vertical to the axis of channel and suction and injection are applied at the wall. The well known equations of MHD have been governed to the motion of an electrically conducting fluid that has been subjected to magnetic field. The numerical solution has been carried out by finite difference approach. By continuum considering of the fluid, it has been seen that the velocity profiles varies because of additional flow injection and suction. The mentioned profile has some difference with non-injection and suction conditions. So that, the results of present numerical simulation shown that the flow injection and suction through the wall can be controlled effectively, the main flow in channel. This phenomenon has engineering importance in some of industrial application. The results have been obtained for different injected and sucked non-ionized flow rate. Finally, comparison of the present result with the finite element method results had shown the good agreement.
