Design and Analysis of Bell-Parabolic De Laval Rocket Exhaust Nozzle

The following paper is about bell-parabolic de Laval shaped rocket nozzle. The paper primarily starts with CADding of the generated geometry, achieved by using RPA software. It then goes on to perform stress, deformation and CFD analysis on it. These analyses were performed to understand the actual nature and performance of the nozzles used in international space missions. CFD was mainly performed in order to produce and assess quantitative prediction of the fluid phenomena pertaining to the rocket nozzle, the analysis was also useful in the process of validating the information gathered from the rocket propulsion analysis software. CFD also helped in producing representation of the flow field since practical implementation of the same would have been cumbersome and difficult to achieve. This project has not only helped to design and analyze one of the most difficult elements in the mechanical industry but also to learn about its core importance.
