Viscous and Joule Dissipations in Hydro-Magnetic Flow of a Nanofluid with Homogeneous-Heterogeneous Reactions and Heat Absorption

Present paper deals with the study of boundary layer hydromagnetic nano-fluid flow past a stretching sheet under the influence of magnetic field, homogeneous-heterogeneous reactions, heat absorption, viscous dissipation, and Joule dissipation. The non-linear partial differential equations, governing the present flow model, are transformed into a system of non-linear ordinary differential equations (ODE) using the suitable similarity transformation. These transformed ODEs are, then solved using Spectral Relaxation Method (SRM).  In order to validate the results obtained by the SRM method, the numerical values of skin-friction co-efficient, rate of heat and mass transfers have been calculated, for different values of magnetic parameter M and Smidth number Sc, using bvp4c routine of MATLAB and found that these values are in excellent agreement with the values calculated through SRM technique. Numerical values of velocity, temperature and concentration distribution for various values of flow parameters have been calculated and presented in graphical forms whereas those of skin-friction co-efficient, Nusselt number at the surface are supplied through the table.
