Cavity in journal bearings
 

Dear all,

I am working on cavitation in journal bearing simulation in a turbulent flow regime.
BCs obtained from experimental investigation are Static Pressure at Inlet and zero guage pressure at both leakages.
When I use mixture model and Zwart-Gerber cavity model, after completion of solution process, although everything goes fine with residuals_namely mass RMS close to 1e-4 limit_, when I check the mass flow rate using report at inlet and leakage there is a considerable error in net rate( near 0.05 kg/sec difference!!!).
I appreciate if anybody could help me with this.
I should also mention this is a part of the whole THD simulation of cavitating flow in a journal bearing.

Regards,
