Abstract: A numerical study is performed to understand the effect of moving wall direction, thermal radiation and nanofluid volume fraction on convective flow and heat transfer of nanofluids in a differential heated lid-driven cavity. The top wall of the cavity is moving left and right direction and it will affect the stream flow inside the cavity. The horizontal walls are taken to be adiabatic. The governing mathematical model is solved by control volume method. The results are presented graphically to know the impact of the dissimilar directions of the moving wall, Richardson number, and thermal radiation. The flow and thermal distribution are strongly affected by the moving wall’s direction.
