Thermal energy transport on MHD nanofluid flow over a stretching surface: A comparative study

This paper deals with heat and mass transfer in an electrically conducting nanofluid flow over a heated stretching sheet. The behavior of heat generation/absorption, thermophoresis, and chemical reaction are also taken into account. To model the equations of momentum, thermal energy, and nanoparticle concentration, suitable similarity transformation variable is utilized. These transformed ordinary differential equations are solved numerically using fourth-fifth order Runge-Kutta methods. The physical significance of all the parameters is discussed and demonstrated via graphs. Furthermore, the skin friction coefficient, Nusselt number, and Sherwood number are also displayed via graphs. It is evident that due to higher values of radiation, the surface heat flux becomes higher so, the temperature of the nanofluid increases in the thermal boundary layer and increase in thermophoretic number and the Brownian parameter, the Nusselt number increases, however, Sherwood number decreases.
