k and epsilon Values for High Pressure Water
 

Hi

I am doing a simulation which involves Passing Gas bubbles in Water(which is stationary) with some velocity.At the atmospheric pressures,I was using k and epsilon values as 0.1 and 0.25 and the results were quite consistent with that of Literature.Now at high pressures,I am not quite getting even close to the results.
Can anyone please suggest the values of k and epsilon at high pressures(around 8 bar) in stagnant water through which gas is rising with some specified Velocity?

Hope you guys would help me out!
