Abstract

The combined free convective dynamic boundary layer and thermal radiation boundary layer at a semi-infinite vertical plate has been studied with variable suction. The fluid is considered to be gray absorbing emitting. The coupled unsteady non-linear momentum and energy equations of the combined layer are then reduced to similarity equations by introducing a time dependent similarity parameter. The similarity equations are solved numerically by adopting shooting method using the Nachtsheirm - Swigert iteration technique. The resulting velocity and temperature distributions are shown graphically for different values of the parameters. The numerical values of the wall shear stress and the heat flux are also shown in tabular form. Finally these results are discussed
