Influence of Second-Order Velocity Slip and Double Stratification on MHD 3D Casson Nanofluid Flow Over a Stretching Sheet

An analysis of three-dimensional magneto hydrodynamic Casson nanofluid flow, heat and mass transfer over a stretching sheet with thermal radiation, heat source/sink, second-order velocity slip and double stratification is carried out in this communication. The governing nonlinear system of partial differential equations is converted to nonlinear system of ODE's by applying similarity transformations. The system is then solved numerically by applying the efficient finite difference Keller box technique. The impacts of various controlling parameters on velocity distribution, dimensionless temperature, concentration profiles, non-dimensional skin friction number, local Nusselt number and local Sherwood number are investigated by using graphical illustrations. Comparison of the current results is done with the previously available literature. A nice agreement is obtained. It has been observed that the fluid is closer to the Newtonian fluid for higher values of Casson fluid parameter. The impact of first-order velocity slip parameter is to reduce the velocity in x direction and enhance velocity in y direction. Exactly the reverse trend is observed with increase in the values of second-order velocity slip parameter.
