THE GOVERNING EQVATIONS AND TURBULENCE MODELS OF COMPRESSIBLE TURBULET FLOW IN A ROTATING FRAME

The governing of equations compressible turbulent flow in the rotating frame are established by the aid of the mass weighted average method.The transport equations for the turbulent stresses,the turbulent kinetic energy and the dissipation rates are derived from the obtained equations.The from of these equations set up in a rotating frame is different from that in an ordinary inertia reference system.The rotating effects caused by Coriolis and the centrifugal forces result in the appearance of the additional iterms in these equations.They may not be ignored in solving the Navier-Stokes equations and studying the turbulence models.Five turbulent models and their mathematical expressions are considered,and their revised forms taking account of the rotating effects are discussed.
