Abstract

This paper presents a simplified formulation for ϵ_H for low to moderate Prandtl number fluids and for ϵ_M that utilizes the surface renewal model, but which also accounts for the fact that eddies do not reach the surface. The predicted trend in Pr_t obtained on the basis of the present analysis suggests an opposite dependency on Pr to that predicted by many of the other analyses.
