### Flow and heat transfer over a stretching surface with variable thickness in a Maxwell fluid and porous medium with radiation

**ABSTRACT**

The effect of thermal radiation on flow and heat transfer of Maxwell fluid over a stretching surface with variable thickness embedded in a porous medium is considered. The governing nonlinear partial differential equations are transformed into a nonlinear ordinary differential equations by using a similarity transformation which were solved numerically with fourth/fifth-order Runge-Kutta method. A comparison of obtained numerical results is made with the previously results in some special cases and excellent agreement is noted. The effects of elasticity, radiation parameter, porosity parameter, wall thickness parameter, and thermal conductivity parameter on the velocity and temperature profiles are presented. Moreover, the local skin-friction and Nusselt number are presented.
