Supersonic Nozzle Flow

Abstract

The nozzle flow is considered to be much more important in aerospace applications. Based on the pressure, velocity and temperature, flow velocity, Mach number and area, the nozzle shape will vary to meet the required condition. Nozzle is a part where the potential energy is converted into kinetic energy. The high pressure and temperature combustion product of gas is converted into high velocity and low-pressure gas as exhaust. In aviation, the main force of thrust is generated due to high velocity exhaust. This chapter gives an explanation and mathematical expression of various nozzles in both subsonic and supersonic flow along with the flow associated issues. The 3D model of convergent chevron nozzle was analyzed for the characteristics of jet mixing and acoustic effect at the exit. These results were compared with the same dimension chevron nozzle with wedges. The added wedges enhanced the jet mixing.
