Simulation of Axisymmetric Free Jet using LRR Reynolds Stress Model
 
1 Attachment(s)
Hi Foamers,
I am trying to simulate a round jet with LRR RSTM. So initially I started the simulation with k-epsilon model and compared with experimental results available in literature. Since the results from k-epsilon model are not satisfactory, I am moving to RSTM model as it is a second order closure for Reynolds Stress.

Coming to the problem, when i start the simulation with LRR model, the solutions start blowing. I just tried with k-epsilon models solution and switched to LRR model but the results are not satisfactory:confused:.

Suggest me some corrections and help me in getting the simulations right.

I have attached the basic case with coarse mesh, which i used for testing k-epsilon model simulations.
