Abstract

The influence of thermal radiation on the problem of mixed convection thin film flow and heat transfer of a micropolar fluid past a moving infinite vertical porous flat plate with slip velocity was dealt with. The fluid viscosity and the thermal conductivity were assumed to vary as a function of temperature. The equations governing the flow were solved numerically using the Chebyshev spectral method for some representative value of various parameters. Comparisons with previously published work were performed and found to be in an excellent agreement. The effects of various parameters on the velocity, the microrotation velocity and the temperature profiles as well as the skinfriction coefficient and the Nusselt number were plotted and discussed.
