چکیده انگلیسی
In this article, heat transfer analysis of an unsteady oblique stagnation point flow of elastico-viscous Walter's B fluid over an oscillating-stretching surface, heated due to sinusoidal wall temperature is presented. The governing partial differential equations are transformed into dimensionless form. The solution of obtained partial differential equations is computed numerically using Chebyshev Spectral Newton Iterative Scheme (CSNIS). The computed results are highly accurate and compared with previous studies in limiting sense. The effects of involving parameters on the fluid flow and heat transfer are shown through tables and graphs. It is importantly noted that the amplitude of the local Nusselt number and skin friction coefficient enhances due to increase in the values of unsteady parameter. The heat transfer rate increases, with increase in the values of Prandtl number. In non-Newtonian fluid, the heat transfer rate decreases as compare to Newtonian fluid case. The variation of skin friction coefficient and local Nusselt number are discussed for the wide range of time and various pertinent parameters.
