Numerical appraisal of the unsteady Casson fluid flow through Finite Element Method (FEM)

An efficient numerical method is offered to discuss the effects of variable heatflux, viscous dissipation, and the slip velocity on the viscous Casson heat transfer(CHT) because the unsteady stretching sheet taken into reckoning the effect ofheat generation or absorption. The finite element method (FEM) is applied tosolve the resulting the ODEs which describe the problem. The effect of the factorsgoverning the HT such as unsteadiness parameter, slip velocity parameter, Cassonparameter, local Eckert number, heat generation parameter and the Prandtl numberare explored and given. Also, the local skin-friction coefficient and the local Nusseltnumber at the stretching sheet are computed and discussed. Finally, the obtainedsolutions confirm that the given procedure is an easy and efficient tool for assayingthe solution of such fluid models.
