The impact of magnetic-!eld induced force on buoyant "ow in lid-driven cavity is addressed in this work. Two sides of the cavity are moving in opposite directions. The temperature of heating element located on the bottom wall is varied linearly and is mirrored about the mid-point of the wall. The convective heat transfer in the cavity is analyzed systematically using an in-house CFD code. The fundamental aspects of different "ow regimes, the strength and inclination of magnetic !eld are explored. The obtained results reveal strong in"uence of Ri and Ha on the heat transfer characterization.

The convective heat transfer in the cavity is analyzed systematically using an in-house CFD code. The fundamental aspects of different "ow regimes, the strength and inclination of magnetic !eld are explored.
