Özet

A general numerical method for the solution of the complete Reynolds-averaged Navier-Stokes equations for 1D and 2D oscillatory flow is described. The method uses orthogonal/nonorthogonal co-ordinates, contravariant and covariant velocity components and a pressure-velocity-coupling algorithm for staggered grid system. The capability of method and the overall performance of the k-epsilon model are demonstrated by calculations of flow over flat End rippled beds. Numerical tools that will be required for a robust code are examined.
