Abstract

The purpose of the present paper is to investigate the flow and heat transfer of fractional Maxwell hybrid nanofluid on a vertical stretching sheet embedded in a porous medium with the consideration of second order slip boundary condition. The fractional governing equations are numerically solved by the finite difference scheme coupled with L1 algorithm. The effects of Darcy number and slip parameters on the hybrid nanofluid flow and heat transfer are graphically presented and discussed, followed by sensitivity analysis of average skin friction coefficient and average Nusselt number to changes in Darcy number and slip parameters with fractional derivatives increasing. The results show that the impact of Darcy number and slip parameters on the average skin friction coefficient, as well as that of slip parameters on the average Nusselt number is more sensitive to velocity fractional derivative than to temperature fractional derivative. While the effect of Darcy number on the average Nusselt number is sensitive to temperature fractional derivative, but irrelevant to velocity fractional derivative. In addition, the flow and heat transfer are more affected by first order slip parameter than by second order slip parameter.
