Numerical Investigation of Effect of Swirl Flow in Subsonic Nozzle

Abstract

This paper presents numerical investigation of swirling flow through convergent nozzle. The objective of this paper is to determine the exit velocity, thrust and mass flow of the convergent nozzle with respect to Swirl flow passes through it. In this present study swirling flow is induced by axial vane swirler before the entrance region of the convergent nozzle and it is static component which produces medium swirl flow and swirl angle is 30⁰. Three dimensional models are developed using CATIA and meshed in ANASYS.  Using FLUENT solver problem is solved and required results are obtained and compared. It shows a variations and increase in exit velocities compared with nozzle without swirler.
