HEAT AND MASS-TRANSFER IN THE WALL REGION OF TURBULENT FLOWS

A new model for turbulent heat and mass transfer in the wall region is developed. It is based on the energy dissipation rate concept. The energy dissipation rate, which is a parameter characterizing turbulent heat and mass transfer, is evaluated using the hydrodynamic properties of the flow in the wall region. Applicability of the proposed model is examined using the experimental data and correlations for flows on a flat plate, wall jets and flows on a rotating disk. Satisfactory agreement is found between the proposed model and the available experimental data and correlations.
