In this analysis, the stagnation flow conversion problems have been studied for mixed convection heat and mass transfer with electrical magneto hydrodynamic (EMHD) field over stretching sheet by considering nano particles. The physical phenomena varied which depended on various parameters. The important energy conversion parameters are S0 , E, Gt, Gc, Pr, Sc, Ncc, S and δ have constituted the dominance of the electric effect, mixed convection effect, heat, heat transfer effect, mass diffusion effect, heat conduction-convection effect and slip boundary effects, respectively. The similarity transformations and a Runge-Kutta Fourth order method are utilized to investigate the present thermal energy conversion problem. The non-linear ordinary differential equations of the corresponding flow field momentum, temperature, concentration equations and plate sheet heat conduction equation are obtained by availing the similarity transformation technique.

Abstract


In this analysis, the stagnation flow conversion problems have been studied for mixed convection heat and mass transfer with electrical magneto hydrodynamic (EMHD) field over stretching sheet by considering nano particles. The physical phenomena varied which depended on various parameters. The important energy conversion parameters are S0 , E, Gt, Gc, Pr, Sc, Ncc, S and δ have constituted the dominance of the electric effect, mixed convection effect, heat, heat transfer effect, mass diffusion effect, heat conduction-convection effect and slip boundary effects, respectively. The similarity transformations and a Runge-Kutta Fourth order method are utilized to investigate the present thermal energy conversion problem. The non-linear ordinary differential equations of the corresponding flow field momentum, temperature, concentration equations and plate sheet heat conduction equation are obtained by availing the similarity transformation technique.
