The three-layer model has been proposed for the analysis of a two-phase critical flow through a converging nozzle. Most of the previous analyses on a two-phase flow hae been based on a homogeneous or a separated model in their fundamental conservation equations. These results were found with large deviations in the actual measurements for two-phase critical flows. The presented model is assumed to be three-layer flow with a mixing region between gas and liquid phase layers. The numerical results on our proposed model have revealed the effects of the mixing layers on the critical flow. The measurements of the critical flow rate and the pressure profiles were conducted with air-water flow through a converging nozzle. The calculation results of these models have been discussed in comparison with the experimental data for the flow rates and the pressure distributions under the critical condition.
