Abstract

[Abstract]: The development of a new two-dimensional Computational Fluid Dynamics (CFD) solver for structured quadrilateral grid to simulate compressible flow is described. The transonic flow in a diffuser and supersonic flow past an inclined ramp are predicted numerically by solving the full Navier-Stokes Equations (NSE) in coupled manner. The new finite volume CFD solver employs second-order accurate central differencing scheme for spatial discretization and multi-stage Runge-Kutta technique for temporal integration with flow variables stored at the vertices. Artificial dissipations with pressure sensors are introduced to control solution stability and capture shock discontinuity. The predictions have been compared with theoretical solution as well as experimental measurements and good agreement has been found
