Determining the model parameters of a counter-flow hydrodynamical radiating system that correspond to its operating regimes

Acoustic bulletin, Vol. 16 ¹ 3, (2013-2014) p.41-45
A three-parameter model of a counter-flow hydrodynamic radiating system with sound element of the cavitation nature is developed for calculating the fundamental frequencies of oscillations emerging in the system under different operating conditions. This paper deals with determining of the model parameters for whole investigated range of outflow velocities of the working fluid from the nozzle using the method of successive approximations. On this basis, the oscillation frequency and average pressure in the sound generating element are calculated. The obtained results are in good agreement with the experimental data.
