REVISED kappa - epsilon MODEL.

A revised turbulent channel flow is proposed which encompasses turbulent energy, and the dissipation rate of kinetic turbulent energy. The proposed model is valid and is transferable to other two-equation models. This model has a diffusion term which does not exist in the standard model. Similarly, the diffusion term is newly introduced into the channel flow equation. The constants used in the model are estimated using approximate solutions. A numerical example, which shows good agreement with the experimental results, including eddy viscosity distribution, is shown in the paper.
