Investigation of Turbulent Characteristics of a Subsonic Jet Using 3D RANS Simulation

Abstract

Jet aerodynamics is highly dependent on the fluctuating quantities in a flow and determination of these quantities experimentally is very expensive and time consuming. The flow fluctuations associated with turbulence give rise to additional transfer of momentum, heat and mass. In the present work numerical simulations of a turbulent compressible subsonic circular jet of 50mm diameter and Mach number 0.75 using RANS is carried out. Simulations are performed in a three dimensional computational domain and the turbulent model used is SST k-ω. The flow is investigated for axial and radial profiles of velocity components and all the turbulent characteristics. The results are found agreeable with the available results from referred journals. In this work modelling and meshing are done in GAMBIT and the simulations using FLUENT
