Abstract : The aerospace industry is dependent on rocket technologies that allow for reduced prices, more simplicity, and lighter weight while maintaining high performance. A nozzle is a particularly designed duct that accelerates hot gases. The nozzle of a rocket is generally designed with a fixed convergent part followed by a specified divergent section. A convergent–divergent nozzle, typically termed as a de Laval nozzle, does have this configuration. The method of characteristics (MoC) and RAO’s geometry is used to design the de Laval nozzles and, in the current work, the CFD analysis of supersonic flow through two types of nozzles, namely conical and contour (bell) nozzles are done, and the flow characteristics through the nozzle are analyzed for the inviscid, compressible flow conditions. It was found that the bell nozzle provides better shock-free expansion for the given same operating conditions than its counterpart.
