摘要：In this work a modeling of turbulence in the viscous region near a wall is presented, based on two equations turbulence models. This proposal is intended to keep some of the near-wall turbulence physics. Accordingly, an appropriate time scale in the viscous region is used for the kinetic energy dissipation equation and for the turbulence effective viscosity. Because turbulence K-e model gives the correct solution in the logarithmic sub-layer, the proposed modeling uses the solution of this model for the high Reynolds turbulent flow region. In spite of the fact that modeling is ad hoc for attached boundary layer turbulent flow, it is expected to give goods results for non-established boundary layer In this sense some results are shown
