Difference between flash evaporation and cavitation

Click For Summary
SUMMARY

The discussion clarifies the distinction between flash evaporation and cavitation. Flash evaporation refers to the single-stage transition of fluid to gas, while cavitation involves the formation of bubbles in a fluid due to pressure changes. The participants emphasize that these two phenomena are not directly related, particularly in the context of computational fluid dynamics (CFD). The user seeks to model flash evaporation in CFD, indicating a specific application of these concepts in thermal processes.

PREREQUISITES
  • Understanding of flash evaporation principles
  • Knowledge of cavitation phenomena
  • Familiarity with computational fluid dynamics (CFD) techniques

Hi,

what is the differencce between flash evaporation and cavitation ?
Can i apply cavitation model for flash evaporation in cfd ?

Thanks
 
Engineering news on Phys.org
cavitation is bubbles of compressible gas inside of a fluid.
flash evaporation is the single stage fluid->gas transiation.

These aren't 100% related. You mention CFD. Are you trying to make a model for heating fluid to the point it evaporates then computing how the caviation (bubbles formed) effect your process? Otherwise not sure what your end game here is.
 
Thanks for reply
