Mass Flow Inlet - Unrealistic Inlet Velocity
My problem is an ozonation column. Ozone is introduced from the bottom of a cylinder through a sparger. Cylinder has 6 cm diameter and filled with water with 80 cm height.
I have defined my inlet boundary condition as mass flow inlet.
My ozone flow rate is 1 L/min which corresponds to 3.28e-05 kg/s of ozone at my experimental conditions. I set my slip velocity specification method to volume fraction and assigned value of 0.5, which is the porosity of sparger.
However, at the initialization section, my ozone Z velocity is assigned to 0.00589 m/s. I have checked, and this corresponds to the velocity as if there is no sparger and ozone is introduced directly from the bottom.
Do you have any idea how to fix this? Should i change the ozone Z velocity at the initialization according to sparger pore size or something? Or could there be any other way to fix this?
Thank you, best regards.
