MASS AND HEAT TRANSFER RATES FOR LARGE GRADIENTS OF CONCENTRATION AND TEMPERATURE.

Abstract

This report concerns a project in which the problem of large-gradient transfer was reviewed and redefined, experimental data were obtained in well-controlled systems, and return made to an earlier method of analysis which gains in physical generality what it loses in mathematical rigor. Stagnation regions and a completely turbulent boundary layer of a flat plate were chosen as general flow configurations worthy of careful study. In the systems studied attention was forced on physical aspects of the transfer problem, such as simultaneous transfer, variations in transport coefficients, large gradients in concentration and temperature, large concentrations of diffusion component, convection caused by diffusion, and primacy of boundary conditions.
