Turbulent boundary layers with vectored mass transfer

Collier and Schetz (1984) have furnished data that deepens understanding of the subtleties of turbulend boundary layer flows with blowing. In the present effort to quantitatively characterize the various interacting elements of the flow, an approach is proposed for the exploitation of such data in model development. If the Reynolds-averaged equations of motion are locally spatially averaged in horizontal planes, with a scale that is large relative to porosity, yet small relative to boundary layer growth, the discrete jet blowing may be converted into its distributed mass transfer equivalent.
