I'm a phD student working on gas-liquid system. I'm trying to simulate using FLuent 12 a bubble column in which the water flush from the bottom while the gas is injected through holes in the tube. The gas is injected perpendicular to the water.
I'm using the mixture model and using as boundary condition velocity-inlet for both the liquid and the sparger.
I try first to run the simulation introducing also a gas phase where there should be only water in order to introduce gas in the column and then I insert the gas from the sparger. When I insert the gas from the sparger the following errors appears:
turbulent viscosity limited to viscosity ratio of 1.000000e+06 in 538931 cells
131 4.4596e+49 4.2260e-02 5.6916e-01 5.4465e-02 5.9507e+63 9.9264e+42 1.3529e-01 0:00:47 19
# Divergence detected in AMG solver: pressure correction -> Turning off correction scaling!
# Divergence detected in AMG solver: k -> Increasing relaxation sweeps!
what should I do?
thank you in advance
