Rocket nozzles are critical components in rocket propulsion systems because they convert thermal energy
produced in the combustion chamber into kinetic energy to generate thrust. The bell-shaped rocket nozzle is
widely used in modern propulsion systems due to its ability to provide high efficiency with reduced structural
length. This study focuses on the design and computational analysis of a bell rocket nozzle using theoretical
calculations and Computational Fluid Dynamics (CFD). The nozzle geometry was designed using CATIA
software and analyzed using ANSYS Fluent. The CFD simulation was used to determine flow properties such
as pressure, temperature, velocity, and Mach number distribution throughout the nozzle. Theoretical results
were compared with CFD results to evaluate the accuracy of the model. The results indicate that the bell
nozzle effectively accelerates exhaust gases from subsonic to supersonic speeds, resulting in optimized thrust
generation.
