Conclusion Four models have been suggested for the description of a one-dimensional flow with a water-steam-air makeup in a system for accident localization from coolant losses, and three have been suggested with proven hyperbolic properties. The region of application of the homogeneous model and the inhomogeneous model using a correlation for phase sliding is practically the entire two-phase region. The proposed bubble-flow model is applicable up to α≤0.5. It is necessary to determine experimentally the region of application of the model of a highly inhomogeneous dispersed flow made up of air and gas, since the expression obtained for the speed of sound in this flow coincides with the speed of sound in a flow with projectile structure. It is not difficult to obtain steady systems from the three hyperbolic systems of equations. Solving them with respect to the spatial derivatives, one can obtain an expression for the critical mass flow density.
