Abstract:

A new turbulence model, the k-?-S( turbulent kinetic energy-dissipation-Stochastic theory) model, is presented. Instead of the Boussinesq eddy viscosity concept in the k-? -E( turbulent kinetic energy-dissipation-Eddy viscosity) model, the turbulent stochastic theory developed by D. Guoren is used in the K-? -S model. The wall functions which are appropriate to the K-? -S model are deduced. Numerical results of 2-D examples show that the k-? -S model is successful.
