Abstract

In this paper study of Nozzle flow Separation is carried out by simulation of Rocket Nozzle Design made through Autodesk Fusion 360 in ANSYS 2021R1 to investigate the Laminar Regime and Turbulent Regime in the divergent section of nozzle. Flow is analysed throughout the nozzle contour from convergent to divergent sections for its separation from nozzle walls due to boundary layer phenomena to visualize it for Laminar and Turbulent regimes. Nozzle design is made for design Mach No of 2.955 and the flow separation simulations are carried out to investigate the flow regimes.
