A FINITE-VOLUME PROCEDURE FOR THE CALCULATION OF INCOMPRESSIBLE AND COMPRESSIBLE FLOWS IN COMPLEX GEOMETRIES WITH MOVING BOUNDARIES AND FREE SURFACES

In this work an implicit finite-volume method for solving problems of fluid mechanics is presented. The method uses Cartesian velocity components and block structures nonorthogonal boundary fitted grids. The well known SIMPLE-algorithm is employed as a basis for the pressure velocity coupling. The transport equations in integral coordinate free form are discretized with up to fourth order accuracy. The method is extended to predict flows at all speeds. To account for turbulent flows, two equation turbulent models - and - - RNG are implemented. The method can predict two- and three- dimensional viscous flows with free surfaces. A wide range of fluid flow problems have been solved to demonstrate capabilities and efficiency of the presented method.
