HI,
I need your help once again :-)
when I make turbulence "on" in bubbleColumn example for twoPhaseEulerFoam solver I have a divergence quickly.
I thought that the problem comes from turbulence model, so I try the model proposed by Sato and Sekoguchi (1975) . the result is the same (divergence)..

Can someone tell me what is the problem ?
NB: I tried the different Schemes

Dear all,
Can someone tell me what is the problem with turbulence in twoPhaseEulerFoam.
I changed the bubbleColumn example with another one, the result without
turbulence is correct bat when I active the turbulence (with k-epsilon or
k-epsilon modified proposed by Sato) the problem is almost the same, it appears
immediately.
I patch in the inlet k and epsilon like that:
k=3/2(Uref I)
epsilon=Cmu^(3/4) * k^(3/2)/(0.07*dinlet)
(ref: H.K VERSTEEG & W MALALASEKERA)
thank you
