Abstract

The main purpose of this paper is to design a cryogenic engine nozzle with specified dimensions using CATIA V5 software and analyze the nozzle using ANSYS software. The realizable k-ε viscous model was used for calculation and the Hydrogen (H2) had retained as an ideal gas. The CFD simulations were done on the nozzle to find the pressure, density, velocity, and temperature. In the graph, there are 500 points streamlined to show the better result of the nozzle, and the density, velocity, and temperature have been compared with pressure. Experimental and numerical analysis have both been used to study the 3-D nozzle’s performance. A twin bell nozzle created for an experiment moderately rocket engine application is subjected to numerical analysis to determine the impact of film injection on the nozzle’s flows and transitional behaviour. Simulations of the start-up and higher manufacturing regimes of a twin bell nozzle are used to predict its actual flying characteristics. To examine how different parameters affect flow behaviour, coolant is injected into two separate places under varied operating conditions. With and without injection of coolant, modifications in shock interactions and shock patterns are examined during start-up flow.

Keywords: Nozzle, CFD, cryogenic engine, pressure, temperature, velocity, density
