CFD ANALYSIS OF THE FLOW CHARACTERISTICS OF PARABOLIC NOZZLE BY CHANGING THE SHAPE OF NOZZLE EXIT

This paper deals with new design of nozzles which can be used in Aerospace applications called as parabolic nozzles. Parabolic nozzles are actually mechanical devices which produces mechanical energy by converting the thermal and pressure energy produced as a result of combustion. This project aims at providing the flow characteristics of parabolic nozzle by changing the shape of the exit area. The analyses were further extended by changing the pressure values. The analyses processes were carried out using Computational Fluid Dynamics software ANSYS CFX. The result of this study showed that the working nature of the nozzle while changing its exit shape and also the pressure.
