Heat mass transfer of Nano fluids flow with absorption in the presence of thermal radiation

Abstract

This study investigates the effects of chemical absorption on Heat Mass transfer of nanofluids flow over an infinite vertical plate in the presence of thermal radiation and applied magnetic field. the fluid is assumed to be electrically conducting water based Cu-nanofluid. The Tiwari and Das model is used to model the nanofluid, whereas Rosseland approximation is used for thermal radiation effect. Solutions for time dependent velocity, temperature and concentration equations are obtained using Laplace transform technique. The physical quantities of engineering interest such as skin friction, Nusselt number and Sherwood number are also computed. The obtained analytical solutions satisfy all imposed initial and boundary conditions. The effect of various parameters controlling the physical situation is discussed with the aid of line graphs. During the course of computation, excellent result was found from various physical parameters embedded in the problem.
