Аннотация: The work is devoted to experimental investigation of the influence of a gas phase on the self-oscillating regime with the vortex core precession occurring in a twisted flow in the case of a helical type of the decomposition of an axisymmetric vortex. Investigations of the frequency of vortex precession and of the full pressure dropПоказать полностьюover the test section of a vortex chamber depending on the liquid flow rate and gas content were carried out. The relations obtained reveal a number of interesting effects that reflect the specific features in the behavior of precessing vortices with a gas core. These investigations are important, for example, for controlling resonance oscillations occurring in hydroturbines. © 2010 Begell House, Inc.
