On the influence of thermal phenomena during cavitation through an orifice

On the influence of thermal phenomena during cavitation through an orifice

•Upstream pressure and subcooling level have high impact on cryogenic cavitation.•Temperature drop through the orifice increases with the initial subcooling degree.•The orifice cavitates at pressures lower than the saturation one for δTsub
