Analysis of Self-Oscillation Processes in a Cavity with a Flow of OpenType on the Basis of the Data of Vortex-Resolving Calculations

The mechanisms of self-oscillation processes occurring in cavities of open flow type are considered and substantiated on the basis of a detailed investigation of the phenomena of hydrodynamic, flow-rate, wave, and resonance nature. The theoretical conclusions are substantiated by an analysis of the...

Summary:The mechanisms of self-oscillation processes occurring in cavities of open flow type are considered and substantiated on the basis of a detailed investigation of the phenomena of hydrodynamic, flow-rate, wave, and resonance nature. The theoretical conclusions are substantiated by an analysis of the data of numerical experiments performed by different authors.
