Abstract

A numerical analysis has been made on mixed convection in a lid-driven square cavity when both vertical sidewalls are partially heated and cooled in the presence of uniform magnetic field. Three parallel locations and two dissimilar locations for heating and cooling on left and right sidewalls are considered. The top and bottom walls with the remaining locations free from heating and cooling on both vertical sidewalls are considered to be adiabatic. The governing equations are solved by the finite volume method. The resulting effects on combined convection flow and heat transfer for different heating and cooling locations are exhibited graphically for the variations of the Richardson and Hartmann numbers.  The average heat transfer rate enhances in the similar locations than dissimilar locations
