Hello dears!

quick questions:

1-Does anybody have any experience about initializing k and epsilon the jet flow at its nozzle tap? case study is dense jets: jets with higher density than their ambient which they released in.

2-Are those values of k and epsilon at the nozzle of the jet very important to the final results? specifically I am dealing with realizable k-e model and I think this model is in trouble to predicte the eddy viscosity for my test case (dense jets).
