OUTFLOW OF A BOILING LIQUID FROM A TUBULAR CHANNEL UNDER THE ACTION OF A HYDRAULIC FRICTION FORCE

The emptying of a tubular channel as a result of the outfl ow of a boiling liquid from its one end subjected to a sudden seal failure was investigated. The case where the liquid outfl ows from the channel in the sluggish regime in which the lag eff orts are insignifi cant and, consequently, the rate of emptying of the channel is mainly determined by the hydraulic losses and the eff ects of adiabatic expansion of the boiling liquid was considered. It is shown that the system of equations defi ning the outfl ow of the liquid from the channel in the two limiting cases where the hydraulic friction force acting on the liquid fl ow in the channel changes linearly with change in the fl ow velocity and where this force changes by the square law can be reduced to one nonlinear equation. Self-similar solutions of the problem on the sudden loss of the sealing at one end of the channel have been constructed.
