Aiir bubble in water
 

HI,
i need to model air bubble in water and need to find out whether the air bubble is escaping during the circular motion of water through a exit provided at a datum higher than the inlet? can anyone please guide me in anyway for modeling the same? thank you in advance

Do the tutorials provided with CFX - especially the multiphase ones, then do some study on appropriate models.

THANK YOU ghorrocks...I WILL TRY ON IT...

mass-flow rate problem
 

ghorrocks...one more thing i felt in cfx regarding mass-flow rate...we have given a mass flow rate in a face in any problem and analysis is done. after that while checking the the flow rate in the same face in the results i am not getting the given mass-flow rate instead a very low mass flow rate.
i will specify it - i have given a mass flow rate in the outlet of the centrifugal pump and analysis is done .while checking the results it is found that the given flow rate is not obtaining in the outlet y so? if we have given an input it should be the same after the analysis in ordinary cases na? what is the real problem?

while giving the pressure input there is no problem...the given input is exactly showing after the analysis also...

Can you post your CCL?
