Abstract
In the work, based on numerical methods of viscous fluid dynamics, the hydrodynamic interaction of the impeller, guide vanes and the pump-jet guide nozzle were calculated, in addition, the parameters of the hydrodynamic wake behind the submarine body were determined and compared with experimental data. The results of this comparison allow us to conclude about the correctness of the applied calculation model.
The developed method allows calculating the hydrodynamic effects on the elements of the pump-jet propulsion unit under various operating conditions of the impeller. In addition, it is possible to simulate complex unsteady regimes of submarine motion, which, in the process of testing, are associated with considerable technical difficulties. The number of such modes include propulsion reverse of submarine. It is shown that from the point of view of ensuring the parameters of stealth submarine in the hydrodynamic wake, the mode of steady motion of submarine is most preferable. All other things being equal, in a turbulent wake with a zero excess pulse, a faster damping occurs along the wake parameters as compared to a jet in a slug flow (submarine acceleration conditions) or a splatter pattern (submarine braking conditions).
The presented approach allows to increase the efficiency of design work due to a comprehensive multiparameter analysis of the influence of various factors on the hydrodynamic characteristics of the pump-jet propulsion unit and the sign parameters of the submarine.
