Thermal analysis of oblique stagnation point flow with slippage on second-order fluid

Abstract

It is well-established fact that thermal resistance models are highly effective passive devices to transfer large quantities of heat for predicting the thermal performance. In the present investigation, we analyzed the thermal analysis of an unsteady oblique stagnation point flow of an incompressible second-grade fluid on a stretching surface with some slip effects. The governing equations of the model under consideration are presented. The governing PDEs are altered into nonlinear ODEs by utilizing non-similar and similar variables and then solved numerically. The analysis further reveals that these solutions sustain in a definite domain of corresponding parameters. Moreover, the variations in temperature and velocity are presented in graphical form to show the influence of controlling parameters. The numerical details of the heat transfer rate for the several thermophysical parameters and skin friction are illustrated in tabular form. The increment in the local second-grade parameter causes the Sherwood number to decrease. The value of the Nusselt number enhances if we decrease the value of the local second-grade parameter.
