CFD simulation of round turbulent jet
Hello, I am new to CFD and I want to model a round turbulent jet issuing into a quieschent medium. I am wondering what type of turbulence model to use and what boundary conditions would be used. Thanx a lot for your help

What kind of simulation do you have in mind.? DNS LES or ASM

assuming use of RANS. use k-ep even for the free sheer region, modify the stress terms accordingly, dont modify the constants arbitrarily.

Re: CFD simulation of round turbulent jet
Hey What I personally feel and my thesis work was on Jet Impingment,I found recent Durbins V2F turbulence model (RANS) is extremely good and which gives extremly good results.In additon to u K and Eps equation u have two more V2 and f equations.
try to avoid to use K-Eps model for this problem cheers Alex |
turbulent round jet
Hello , I'm making the analysis of a turbulent round jet.The purpose of this case is to validate the performance of the Reynolds Stress Model for turbulence. It's an exercise of ANSYS Fluid Dynamics Verification Manual ANSYS. Anyone already made this analysis, or can help me?
