A REVIEW ON STRUCTURAL BENEFITS OF NOZZLE IN PROPULSION SYSTEMS

Mohd. Anas, Mahmood Alam

Abstract


As a matter of fact nozzles play a very important role in providing the necessary thrust required for very high velocity, to the vehicle with which it is attached. The jet propulsion exhaust nozzle system is an integral part of a turbine engine and critically depends on overall performance. Challenges are associated with the structure, design and manufacturing of an exhaust nozzle to increases the speed of the vehicle. Researchers have worked on different structures and additional features such as variable throat and exit area, jet noise suppression, and reverse thrust. A nozzle also serves to control the direction or characteristics of a fluid flow as it exits or enter an enclosed chamber or pipe via orifice.

In this review paper an attempt is made to collect different structures of nozzle with their construction details and mechanism of performance. The discussion includes a general comparison of performance of different structures of nozzles for particular fluid.
