Numerical Investigation of Fully-Developed Turbulent Flows in Two-dimensional Channel by Stochastic Turbulent Model

In this paper the turbulent flows in two-dimensional channel are investigated and fully developed turbulent flow is assumed. The solution method is presented for this turbulent flows based on application of the Stochastic Turbulent Model (STM). The numerical investigations were carried out at different Reynolds numbers calculated by the half size of the channel and the average velocity. The one-equation version of Stochastic Turbulent Model (1E-STM) proposed by Czibere [2] predicts very well the distributions of the turbulent velocity profiles in the turbulent flows comparing with measured data taken by Laufer [3].
