Unsteady Casson Fluid Flow Past a Stretching Sheet Subject to Non Linear (Quadratic) Free Convection Along with Suction

In the present study, quadratic (Non linear) free convection of Casson fluid flow past a stretching sheet with suction is considered. The fluid which is subject to non-zero initial flow is subject to sudden application of non linear free convection and suction. Mathematical forumulation is carried out for the flow behavior. The governing equations hence obtained are non-dimensionalized. The non-dimensionalized governing equations along with their non-dimensionalized initial and boundary conditions are solved using the well-known Crank-Nicolson type implicit finite difference technique. Plots are described to understand the effects on the dependent variable namely, velocity and temperature along with local skin friction and local Nusselt number. It is observed that the velocity increases with suction.
