Abstract

  • In this study, a 2D numerical analysis is conducted in to investigate hydrodynamically and thermally developing flow of an electrically conducting, viscous, incompressible, and Newtonian fluid between the parallel plates a under uniform magnetic field. The problem geometry consists of two electrically insulated parallel plates of which one is stationary, and the other one is moved at a constant velocity. The fluid is heated by applied constant heat flux at the walls, and an external uniform magnetic field is applied perpendicular to the flow. Two different cases have been investigated under thermal boundary conditions: uniform heat flux at the moving wall and an adiabatic stationary wall (Case A) and uniform heat flux at the stationary wall and adiabatic moved wall (Case B). Heat generation from viscous dissipation and Joule heating are also included in the analysis Computations are performed via ANSYS 16.0. In the flow region, magnetohydrodynamic (MHD) fluid flow and heat transfer, caused by the interaction of fluid movement and electromagnetic field, are examined. For different wall velocities and heating conditions, the influence of Brinkman and Hartmann numbers on the velocity and temperature profiles and Nusselt numbers are presented.
