Abstract:

A relatively basic study of surface mass transfer effects in a non-reacting binary fluid was conducted. The more significant findings are At least one of the surface boundary conditions employed in the extensive analytic boundary layer literature on the subject is generally an incorrect representation of the physical conditions actually existing at the surface. A reformulation rectifying this deficiency is recommended. The concept of a volumetric displacement mechanism of effectiveness of injected low molecular weight gases, previously found by the author to be appropriate for zero pressure gradient boundary layers in a steady flow field, is applicable no matter whether the flow fields be steady or unsteady, potential or viscous, creeping or boundary layer, etc. Aerothermochemical similarity is a fundamental attribute of turbulence with light-gas injection.
