Abstract

A new simple integral method has been developed and applied to boundary layer flow involving mass transfer. The original Karman-Pohlhausen was refined by effecting a second integration of the momentum equation in order to arrive at a basic differential equation for the determination of 6Cx).A computer code (SIM code) has been developed and its application extended to a case of great interest; porous flat plate with similarity plowing using polynomial velocity profiles of constant- and variable-cpefficients. Reaspnable agreement with other existingresults is obtained. This method is sufficiently simple to be of practical use.
