Abstract

The engine's interpretative thrust production, such as nozzles, has been restructured for higher staging. Modern expansions of combustion systems, such as rocket nozzles, will be adjusted to meet the needs of today's applications. The bell and dual bell nozzles are an example of such advancements. From the four fundamental types of bell nozzles, one such bell nozzle is chosen. The parabolic shape optimised the thrust of an axisymmetric nozzle. The basic goal of constructing a bell nozzle is to produce as little shock waves as possible. A dual bell is explored and studied in this work using CFD flow. The main focus is on the design and analysis of dual bells based on altitudes ranging from 2, 5, 7, 10, 12, 15, inlet mass flow rate of 5 kg/s, inlet temperature of 1200 K, and NRP value of 12. We had performed simulation to the design and flow simulation with the help of SolidWorks 2020 by adjusting the value of inlet pressure of the fluid and calculating with the help of ambient pressure with regard to altitude. Flow simulation is done in a three-dimensional model.
