【 摘 要 】

In this paper, the degassing process in a swirling chamber as a function of the pressure drop, the diameter and length of the nozzle, and the mass flow velocity was considered. On the basis of the equations of the velocity of the pressure drop in the nozzle and the Rayleigh-Lamb equation describing the gas bubble growth, the dependence of the pressure change in the nozzle on time was obtained and the critical area was determined in which the formation of gas bubble nuclei occur. The condition of avalanche increase in gas emission in certain intervals of the nozzle length is obtained and its optimum value is determined. This condition makes it possible to realize the mechanism of heterogeneous and barrier-free gas evolution in a swirling chamber.
