The internal flow dynamics of a solid propellant rocketmotor (SRM) is very complex. The performance of asolid rocket motor depends heavily on the flowcharacteristics, the chemical composition of the grain,the temperature distribution and the combustionproducts. In this study internal ballistics of some solidrocket motors (SRM) are numerically simulated. A CFD simulation of the flowfield within a solidpropellant rocket motor with slightly tapered grainhas been developed. Also in this study the effect of erosive burning is investigated. Governing equations ofaxisymmetric inviscid flow are solved using an explicitMacCormack finite difference technique in which thelocations of shock waves are captured by the solutionscheme
کلمات کلیدی: solid rocket motor, tapered grain, erosive burning, MacCormack scheme
