Magnetohydrodynamic (MHD) nonlinear convective flow of Jeffrey nanofluid over a nonlinear stretching surface with variable thickness and chemical reaction

Main purpose here is to analysis magnetohydrodynamic (MHD) nonlinear convective flow of Jeffrey nanofluid by a nonlinear convectively heated stretching sheet of variable thickness. Nonlinear thermal radiation, heat generation/absorption and chemical reaction are considered. Brownian motion and thermophoresis have been utilized in energy and concentration expressions. Recently suggested condition employing volume fraction of nanoparticle at the surface to be controlled passively rather than actively is utilized. Appropriate variables lead to development of nonlinear ordinary differential systems. Effect of various pertinent variables for velocity, temperature and nanoparticle concentration have been displayed and explored. Skin friction coefficient and local Nusselt number are calculated and addressed. It is revealed that larger values of relaxation and retardation times ratio diminish velocity distribution. Moreover impact of heat generation/absorption on the temperature and heat transfer rate are quite reverse.
