what is cavitation and flashing
Flashing is a vaporizing process similar to cavitation. However, flashing differs from cavitation in that the vapor phase persists and continues downstream because the downstream pressure remains at or below the vapor pressure of the liquid.o avoid dangerous and costly problems in their process systems industrial valve users should understand the basics of the ways in which cavitation and flashing affect control valves.
Cavitation is a significant cause of wear in some engineering contexts. Collapsing voids that implode near to a metal surface cause cyclic stress through repeated implosion. This results in surface fatigue of the metal causing a type of wear also called cavitation.n man-made objects, it can occur in control valves, pumps, propellers and impellers. Non-inertial cavitation is the process in which a bubble in a fluid is forced to oscillate in size or shape due to some form of energy input, such as an acoustic field.
