MHD stagnation point flow of micropolar nanofluid between parallel porous plates with uniform blowing

Abstract

The combine effect of nanoparticle and magnetic field on a micropolar fluid flow between two parallel coaxial porous plates with uniform blowing is investigated in this article. The two kinds of Nanoparticles, i.e. Copper Oxide (CuO) and Alumina (Al 2 O 3 ) are mixed with base fluid water to prepare the mixture of microplar nanofluid for the analysis of this problem. The convergence analysis of the numerical solutions is considered for large mesh size and high tolerance error. It is interesting to note that the skin friction coefficient at the lower plate increases with increasing the magnetic field for both CuO − water and Al 2 O 3 − water micro-polar nanofluid but it decreases with increases in volume fraction of nanoparticles in both the fluids. A novel result is found from this analysis that the rate of heat transfer at the lower plate increases with increasing the either magnetic parameter or micro-rotation parameter or the volume fraction of nanoparticles in the case of both fluids. The effects of magnetic field and micro-rotation parameter on the velocity, micro-rotation, temperature and concentration profiles are analyzed. The radial velocity profiles increase near the stagnation point but decreases near the plates by increasing the blowing parameter.
