Abstract: This study is for incompressible flow at constant viscosity. It consists of a numerical simulation and an experimental validation for a boundary layer generated by a turbulent flow on a hydraulically smooth bed. The device considered here is a hydraulically smooth plate of length 15 m and of 0.27 m high. The study treats the influence of the reynolds number on the thickness of the boundary layer, on the turbulent of friction and on the longitudinal velocity into the boundary layer. This problem was approached by using gambit calculation code to generate the mesh. These one adopted here is the structured type which is very narrow at the bottom level of the plate. Researchers used also fluent code to solve the general equations of the boundary layer. The system of equations being the open type, we are forced here to use the k-ε Standard Turbulent Model. The results obtained shows that there is a good concordance with the experimental results and thus Validates Model.
