Cavitation model by A.K. Singhal
 
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.

Can you share the paper which has the caviation model in it so that i can have a look at the dimension

regards
