Coefficients for the combined heat- and momentum-transfer in laminar and turbulent boundary layers

Mass transfer effects on the heat and momentum transfer characteristics of laminar boundary layers, determined through the numerical integration of boundary layer equations, have been experimentally confirmed in recent years. In addition, normal-to-wall flow and carrier gas flow properties have been determined. The analysis of the boundary layer numerical solution yields the dimensionless physical property numbers epsilon(f) and epsilon(H) for momentum and heat transfer, respectively, which are generally capable of accurate transfer coefficient descriptions. In the case of turbulent boundary layers, film theory corrective factors for heat and momentum transfer have been obtained from experimental results reported in the literature which depend, in the first approximation, on the single parameter, epsilon(turb).
