Default Gas flow profiles in mixing tank
Posts: n/a
My system is gas sparging in solid liquid system. The system consists of one inner cylinder which is a solid and a outer cylinder is filled with water up to a certain height. The inner cylinder also acts as a gas induced impeller. Here gas is evolved at the inner cylinder surface.

The gas profiles evolved are attached to the inner cylinders surface. where as the experimental profiles shows that the profile is away from the inner cylinders surface.

I tried with different turbulence models but there is no change in the gas profiles.

Kindly, give me the solution to this problem.
