AB - In the present study, numerical simulation of magnetohydrodynamic (MHD) mixed  convection heat transfer and fluid flow has been analyzed in a lid-driven  enclosure provided with a constant flux heater. Governing equations were  solved via differential quadrature (DQ) method. Moving wall of the enclosure  has constant temperature and speed. The calculations were performed for  different Richardson number ranging from 0.1 to 10, constant heat flux heater  length from 0.2 to 0.8, location of heater center from 0.1 to 0.9, Hartmann  number from 0 to 100 and aspect ratio from 0.5 to 2. Two different magnetic  field directions were tested as vertical and horizontal. It was found that  results of DQ method show good agreement with the results of literature. The  magnetic field was more effective when it applied horizontally than that of  vertical way. In both direction of magnetic field, it reduced the flow  strength and heat transfer. Thus, it can be used as an important control  parameter for heat and fluid flow.
