Computational and Investigational Proportional Flow Study on Cd Nozzle

Abstract

As part of our study , we had to design, produce, and test a convergent-divergent type nozzle with a specific area ratio. The goal of this project is to replicate the operation of a converging-diverging nozzle, which is possibly the most significant and fundamental piece of engineering hardware involved with propulsion and high-speed gas flow.For this, we first examined a specific area ratio. Three distinct designs are constructed for the given area ratio (convergent, divergent, and convergent divergent).The flow through the nozzle is analysed under various back pressure situations. Then, using the values obtained from the analysis, we constructed the nozzle and evaluated its operation. We also tested the choke conditions under varied back pressures and the mass flow rate that corresponds to it. Finally, we plotted the curve of mass flow rates vs. pressure distribution with practical values. Thus, with the assistance of our department faculty, we successfully accomplished this assignment.
