Application of a new version of the k-W model of turbulence to a boundary layer with mass transfer

The prediction of heat transfer from a porous flat plate with a range of blowing and suction through the surface using a k-W turbulence model is described. The effects of mass transfer on the law of the wall are taken as obeying the Jayatillaka correlation. Agreement between predicted and measured variations with the length Reynolds number of the Stanton number is satisfactory even at strong suction rates, as a result of the use of sublayer resistance factor which ensures that the asymptotic limit is approached for these cases. For strong blowing results, the Stanton number limit is zero and its behavior is adequately predicted.
