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 eld. 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 nite volume method.
The resulting efects on combined convection
ow and heat transfer for dierent 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
