Abstract
The emptying of channels and reservoirs filled with boiling up or gas-saturated liquid is theoretically studied within barotropic equations of state. It is assumed that phase transitions occur in the equilibrium mode. Analytically and numerically obtained solutions are used to analyze the effect of initial temperature in the reservoir in the case of boiling up liquid, as well as of the Ostwald absorption coefficient for gas-saturated liquid, on the parameters of flow at the outlet from channels and reservoirs. For the final stage of emptying of channels, where the inertial force is unimportant, a self-similar solution is constructed with due regard for the inversion of flow from bubbly-foamy to vapor-droplet. The effect of inversion on the intensity of emptying is investigated.
