Modeling & Simulation of supersonic Flow in 2D Nozzle Using MacCormack’s and Upwind Methods

In this work, two-dimensional inviscid supersonic flow in nozzle has been investigatedusing CFD schemes and characteristics method. The employed scheme is MacCormack’sfinite volume method. Our own code CHARMAC, was written using MATLAB environment.Standard boundary conditions and the grid parameters were considered to solve the problem.Before analysing the flow by CFD method, we obtained the ideal nozzle geometry using themethod of characteristics for a 2D divergent Nozzle. Using 2D nozzle flow relations, anoptimal throat area is found. At the end we compare the results with the advection upstreamsplitting Method (Ausm) and Fluent.
