CONCEPTUAL DESIGN AND SHAPE OPTIMIZATION OF A PINTLE NOZZLE

The nozzle is usually applied to accelerate and expand or compress the fluid. It is generally used to control the rate of flow, velocity, and pressure. The shape of the nozzle also plays a vital role in the process. Simply a nozzle is a tool that extracts the entering fluid which may be a gas or a liquid and rises its velocity. A nozzle can be a channel or canal or tube or pipe that helps in modifying the speed of the stream of fluid. We have convergent and divergent or both convergent-divergent types of nozzles. Ans also the varying cross-sections of the area of the nozzles affect the speed of the fluid. That means when the area of the nozzle is reduced the rate of nozzle fluid raises and in the same way as the area of the nozzle is raised or increased then the rate of nozzle fluid is reduced. The paper concentrate on the study of flow in nozzles. And the application of the nozzles for different shapes of pintle to increase the performance of propulsion.
