Development of a General-Purpose Compressible Flow AnuPravaha Based Solver using an Implicit Method (Fluids and Energy Systems)

With India focussing even more on Aerospace applications, research and development in compressible ow has received a boost in the country. We aim to develop a general-purpose and robust compressible ow solver to help in research in Aerospace problems. In this thesis we aim to develop a general-purpose and robust compressible ow solver using the implicit MacCormack scheme infinite volume formulation. A system of unsteady Navier-Stokes equations are integrated to a steady state solution utilizing MacCormack's implicit numerical scheme. A new implicit boundary treatment was introduced in the MacCormack implicit scheme. The scheme is unconditionally stable and does not require solution of large systems of linear equations. It is shown that the upgrade from explicit MacCormack scheme, previously implemented in the solver, to an implicit one is very simple and straightforward.
