The fractional Maxwell hybrid nanofluid flow and heat transfer induced by a vertically stretching plate in porous media is studied with the consideration of second-order slip boundary condi-tions.The boundary layer governing equations are established through fractional shear stress and frac-tional Fourier law.Then the finite difference combined with L1 algorithm is adopted for numerical solu-tion.When the fractional derivative parameters change,the sensitivity of flow and heat transfer to each physical parameter is graphically displayed and analyzed in detail.The results show that the impact of Darcy number and slip parameters on the average skin friction coefficient,as well as that of slip pa-rameters on the average Nusselt number is more sensitive to velocity fractional derivative than to tem-perature fractional derivative.While the effect of Darcy number on the average Nusselt number is sen-sitive to temperature fractional derivative,but almost irrelevant to velocity fractional derivative.In ad-dition,the flow and heat transfer are more affected by first order slip parameter than by second order slip parameter.
