The evolution of the entrainment coefficient β of the rotating fluid in a rotor–stator cavity with an inward throughflow and pre–rotation is studied according to the flow parameters. This paper describe a numerical study of flow in such system. As 3D computations involve long computing times and large resources , a simplified axisymmetric model has been used to study the effects of flow parameters on flow in this system .This allows the effects of the main nondimensional parameters on the flow in the system to be studied with computing times reduced by a factor of around 7 compared with 3–dimensional computations .Measurements are obtained in water for a turbulent Batchelor type of flow with two separated boundary layers on the rotating and stationary disks .The computed results are compared with available measured data performed by S.Poncet,M.P.Chauve [1]. The results have good agreement with experimental data.<\div>
