摘要：

This paper presents an investigation of the influence of variable viscosity, variable thermal conductivity and thermal radiation on mixed convective flow due to a vertical wavy surface immersed in a fluid saturated Darcy porous medium. The viscosity and thermal conductivity of the fluid are assumed to be varying with respect to temperature. The Rosseland approximation is used to describe the radiative heat flux. The governing flow, momentum, energy and concentration equations are transformed into a set of ordinary differential equations using the similarity transformation and then solved numerically. The obtained results are compared with previously existing results admit an excellent accuracy. The effects of various physical parameters on velocity, temperature and concentration as well as Nusselt number and Sherwood number are presented graphically in two cases, i.e., aiding flow and opposing flow.
