Calculation of 2D compressible flows using a pressure based finite volume algorithm

The basic idea of pressure based method to predict compressible flows solving the governing partial differential equations for the conservation of mass , momentum and energy , coupled to the thermodynamic equation of state have been demonstrated to work in principle in n earlier work. But the algorithm and the computer code developed were validated only against analytical isentropic calculations for quasi 1-D adiabatic flow in variable area ducts at different flow speed ranges , with nd without shock 13; The present work goes step further , in extending the algorithm for - viscous compressible flows employing non-orthogonal , body fitted coordinate system , cell centered variable arrangement (non-staggered or collocated) and Catesian velocity components for complex , irregular boundaries. The full Navier-Stokes equations have been incorporated , including the energy equation , with all the viscous terms. The inflow/outflow boundary conditions for compressible flow have been implemented in generalised user friendly manner. finally ,the code has been validated against few internal flow situations , e.g . subsonic flow over a bump in a channel and flow through a converging diverging nozzle for which numerical and/or experimental results are available in open literature
