This paper reports multiple slip effects on MHD unsteady flow heat and mass transfer over a stretching sheet with Soret effect; suction/injection and thermal radiation are numerically analyzed. We consider a time-dependent applied magnetic field and stretching sheet which moves with nonuniform velocity. Suitable similarity variables are used to transform governing partial differential equations into a system of coupled nonlinear ordinary differential equations. The transformed equations are then solved numerically by applying an implicit finite difference method with quasi-linearization technique. The influences of the various parameters on the velocity temperature and concentration profiles as well as on the skin friction coefficient and Sherwood and Nusselt numbers are discussed by the aid of graphs and tables.

A mathematical model has been developed to study the Joule heating effect on mixed convection MHD dissipative and radiative flow of an incompressible Jeffrey fluid due to a stretching sheet with power law heat flux, heat source/sink and suction. Similarity transformations are adopted to acquire ordinary differential equations from the governed partial differential equations. Series solutions are procured for these ordinary differential equations by admitting homotopy analysis method (HAM). A decisive way of convergence of series solutions is also provided. Characteristics of dissonant parameters on velocity, temperature, skin friction coefficient and Nusselt number are collected and discussed through graphs and tables. It is seen that the velocity enhances with an increase in Deborah number. Further the temperature is a depreciating function of Deborah number.

In the present paper, we investigated mathematical model of the magneto hydrodynamic flow and heat transfer in an electro-conductive polymer on the external surface of a sphere under radial magnetic field is presented. Thermal and velocity (hydrodynamic) slip are considered at the sphere surface via. modified boundary conditions. The non-dimensional, transformed boundary layer equations for momentum and energy are solved with the second order accurate implicit Keller box finite difference method under appropriate boundary conditions. Validation of the numerical solutions is achieved via benchmarking with earlier published results. The influence of Weissenberg number, magnetic body force parameter, thermal slip parameter, hydrodynamic slip parameter, stream wise variable and Prandtl number on thermo fluid characteristics are studied graphically and via tables. A weak elevation in temperature accompanies increasing Weissenberg number whereas a significant acceleration in the flow is computed near the sphere surface with increasing Weissenberg number. Increasing thermal slip strongly decreases skin friction and Nusselt number. Skin friction is also depressed with increasing magnetic body force parameter. Increasing momentum slip is observed to decrease skin friction. Nusselt number is reduced with increasing Weissenberg number. Skin friction is increased whereas Nusselt number is reduced with greater stream wise coordinate. The study is relevant to smart coating transport phenomena.
