Abstract

This article proposes the numerical model to investigate the impact of the radiation effects in the presence of heat generation/absorption and the magnetic field on the magnetohydrodynamics (MHD) stagnation point flow past a radially stretching sheet using the Casson nanofluid. The non-linear partial differential equations describing the proposed flow problem are reduced to a set of ordinary differential equations (ODEs) via suitable similarity transformations. The shooting technique has been used to obtain the numerical results with the help of the computational program language FORTRAN. The effects of pertinent flow parameters on the non-dimensional velocity, temperature and concentration profiles are presented in tables and graphs. From the results, it has been remarked that the heat transfer rate escalates for the larger values of the radiation parameter for the Casson nanofluid.

Keywords: Casson nanofluid, thermal radiation, MHD, Stagnation point, Nanoparticles.
