Near Wall

An eddy viscosity formula is proposed for turbulent boundary layers in pressure gradients which is compatible with the slope and intercept of the log law. By having a “y3” variation at the wall the formula is suitable for momentum, heat and mass transfer.

This paper describes a general method for calculating turbulent boundary layers with and without mass addition. The method, as in earlier studies, is based on the eddy-viscosity concept. However, the eddy-viscosity formulation presented in this paper differs from the previous ones in that the previous eddy-viscosity formulation has been generalized to handle flows with mass transfer. A large number of flows computed with this method show good agreement with experiment.
