 January 17, 2012, 05:42 Cavitation model by A.K. Singhal #1 New Member   neetu kumari Join Date: Mar 2011 Posts: 14 Rep Power: 7 Hello everyone To simulate the cavitating flow, FLUENT has used A K Singhal's full cavitation model. But the model equations for rate of evaporation or condensation has inconsistency in dimensions. The correct unit of rate of evaporation or condensation should be kg/m3.s, but according to the above mentioned model equations the unit of that particular rate is coming as kg/m4 (by assuming that the empirical constants are dimensionless). If empirical constants have unit then what its value in particular SI unit and if not then how this could be possible? If I have some misconceptions then please help me out. Thank you.

Here is the full reference of that paper.
