Yu.M.Dudzinskii Dynamics of a submerged conical axisymmetric jet shell |
Acoustic bulletin, Vol. 9 ¹ 3, (2006) |
| Natural oscillations of an elastic flooded conic jet shell of a circular cross-section are considered as a model of a counter-flow axially symmetric hydrodynamic radiator. The fundamental harmonic frequency is calculated as a function of geometric and hydrodynamic parameters of the jet shell. The principal possibility is shown for gradual tuning the fundamental harmonic of the acoustic signal by changing a nozzle-reflector working pair, varying the distance between the nozzle and reflector, and regulating jet velocity at a nozzle outlet. The theoretical data are compared with experimental results. |
