Numerical Investigation of the Perfomance of Convergent Divergent Nozzle (original) (raw)

The main objective of the work is to analyse the performance and flow characteristics of convergent divergent nozzle and also to compare the numerical values of the two methods i.e "HIT & TRIAL METHOD" AND "ANALYTICAL METHOD". In this paper we have determine the location and strength of normal shock wave in the divergent portion of the nozzle under varying operating conditions and with different nozzle geometry. KEYWORD: Mach number, Sub-sonic, Super-sonic, Sonic, Compressible flow, Throat. I. NTRODUCTION A nozzle is a relatively simple device, just a specially shaped tube through which hot gases flow. However, the mathematics, which describes the operation of the nozzle, takes some careful thought. Nozzles come in a variety of shapes and sizes. Simple turbojets, and turboprops, often have a fixed geometry convergent nozzle as shown on the left of the figure. Turbofan engines often employ a co-annular nozzle. The core flow exits the centre nozzle while the fan fl...
