PLATE WITH MASS TRANSFER

The effect of radiation on the flow past an impulsively 
started vertical plate in the presence of mass transfer is analyzed. 
The fluid is a gray, absorbing-emitting, and nonscattering medium 
and the Rosseland approximation is used to describe the radiative 
heat flux in the energy equation. A rise of the velocity due to the 
presence of a foreign mass is observed. An increase in the Schmidt 
number (Sc < 1) and in the radiation parameter N leads to a decrease 
in the velocity. The skin friction increases due to the presence of 
a foreign mass when Sc < 1 and decreases at Sc = 1.
