Dispersion Prandtl Number in Mixture Mutliphase Model
 
Hi,

I am using mixture multiphase model to model an axisymmetric turbulent jet.I am using K-e model.Does any one have any idea what is the value of the dispersion number that i need to give.Practically any number should work based on the info given in manual,small numbers should give more dispersion and large number should give less dispersion I am working on 0.3x2.0 domain and Inlet is 0.01, I want to know how dispersion varies by varying this number ,I am using volume fraction of my largest phase as 1,
I am trying to simulate the water jet issuing into an quiescienent air.

Thankyou
