Plz urgent help
 

Hi all,

can any body help about bubble columns. i have one doubt in bubble column(gas-liquid system). my system contains two cylinders first one is inner cylinder and second one is outer cylinder. In my system the gas is evolved at the surface of inner cylinder. the gas flow profile obtained from cfd simulations(eulerian multiphase model) is near the surface of the inner cylinder but in experimental results the gas flow profiles is away from the surface of the inner cylinder.

Could anyone help me with this please?
