Popis: A numerical study of hydromagnetic radiative stagnation point flow of micropolar nanofluid passed through a shrinking sheet is reported. Magnetic field is utilized in transverse direction. Nonlinear system of partial differential equations is converted into system of nonlinear ordinary ones by applying similarity transformations. Convective types of boundary conditions are applied on temperature and concentration. RKF45 technique is applied to investigate the numerical results of different dimensionless physical parameters in graphical and tabular forms. It is visualized that the increasing values of Biot numbers correspond to enhancement in temperature and nanoparticle volume distributions. Further, we observed that the increasing values of thermophoretic and Brownian motion parameters have reverse effects on nanoparticle volume fraction. Keywords: Micropolar nanofluid, MHD, Shrinking sheet, Brownian motion, Thermophoresis
