A CALCULATION METHOD OF NUMERICAL SOLUTION OF REYNOLDS-AVERAGED NAVIER-STOKES EQUATIONS FOR SHIP STERN FLOW

In this paper the application of an improved separated-layers finite analytic method (FA method) is made in the three-dimensional body-fitted coordinate system of a ship hull, to solve numerically the complete Reynolds-averaged Navier-Stokes equations. which are closed by the k-epsilon modelling. The Poisson equations for the grid transformation are also discreted by the FA method, and the moving boundary conditions, the arc-length transformations and linear interpolation techniques are used to control the grid density near the ship surface and within its region. In addition, under the unstaggered grids, a kink of SIMPLEM algorithm for coupling pressure and velocity is dealt with by the FA method. A Wigley parabolic hull and a LFM mathematical hull are used as examples. The former examines the validation for the calculation, the latter discusses the influences on the ship stern flow fields on changing the block coefficient Cb and the degree of UV of the afterbody section with the unchanged forebody.
