My problem consists of a closed tank with half filled liquid with remaining filled with pressurised air!! tank consists of one baffle plate to reduce the turbulence. the inlet s going to be a pipe attached to the tank! so how to define the liquid and gaseous region separetly in the tank?

and also wat kind of turbulence model can be given if the liquid is having reynolds no of 13000?

In 12.1 one define your air and your water as two continuos fluids. Acitvate free surface model.

K-eps should be most stable, SST should work also.

Use the SST turbulence model for all turbulence modelling unless you have a good reason not to. My opinion is SST is the baseline turbulence model now and has superseded the k-e model.
