A computational study on the effect of magnetohydrodynamic mixed convection nanofluid flow in a square split lid driven cavity with block placed near bottom wall is undertaken. Two different nanoparticles gold and alumina are considered for study. The observations obtained by solving non-dimensionalized governing equations Finite Element Method variational approach as accessible FreeFEM++ software. results Prandtl numbers ( Pr), Richardson number Ri), volume fractions [Formula: see text], Reynolds (Re), MHD parameters (M) displayed through graphs figures. It has been observed that pressure distribution significantly increases increment but both behave differently. magnetic field enhancement M = 0.1, 0.2, 0.5 0.9) decreases velocity within cavity. convective heat transfer faster case Re) 100 than 14 or 21.
