A new setup allows us to experiment initially subcooled two-phase critical flows with five different fluids: water, R11, methanol ethyl acetate and butane. We verify that good estimates of the mass flow rate can be derived from the extended HEM for all of the fluids in high subcooling conditions (within ± 20% accuracy). In low subcooling conditions, a satisfactory agreement (± 30% accuracy) with the DEM or HEM predictions is found. This means that the main phenomena involved seem to be correctly taken into account.
