Abstract : This Memorandum presents a simplified analysis of binary boundary-layer flow on a flat plate. A simple computational method previously used by Meksyn has been extended and applied to the present problem. Analytical formulas of skin friction, surface mass transfer, and heat trans fer are derived. The effects on skin friction of various parameters, such as P (Prandtl number), L (Lewis number), and molecular-weight ratio, and heat transfer in binary boundary layers are exhibited explicitly in these analytical formulas. The results agree well with more exact numerical calculations. In addition, some int coupling of viscosity, heat con duction, and diffusion is exhibited-for ex ample, coupling between recovery temperature and skin friction, and coupling between conduc tive heat transfer and diffusion effects.
