Reply To: The energy problem when solving cavitation in FLUENT

[javat33489]

It’s clear, if I just turn on the power and set the temperature to 90, the fluent will calculate that way, the pump cavity will simply be filled with liquid with a temperature of 90 degrees, and there will be no difference in the calculation. You can go in two ways, cavitation or evaporation. So, cavitation, does it make sense to count it in this case? 90 degrees is a temperature close to boiling, it may be more legitimate to calculate with the condition of evaporation and see if the pressure drops below atm, there is a vacuum, there is possible cavitation, and if the pressure is ok, then we conditionally conclude that the pump should be pumped at this temperature can work. But the water doesn't have to boil. If there were no bubbles at the inlet, it will not boil, then cavitation and evaporation calculations are not needed. Am I right sir?
