Abstract

The work deals with the experimental study of precessing vortex in the gas-liquid swirl flow. The data on flow visualization are presented, dependences of precession frequency and pressure drop on the gas flow rate are determined, and correlation between these characteristics, which undergo abrupt changes at low gas contents, is determined. The main effect determining the nature of evolution of the flow parameters relates to the fact that due to strong flow swirl, phase separation with formation of a hollow vortex with the gas core occurs.
