| Summary: | Object and purpose of research. Numerical prediction of hydrodynamic noise induced by flow interaction with non-uniformities of a surface. Materials and methods. The problem is solved by means of hybrid numerical simulation methods for turbulence and direct simulation methods for pseudo-acoustic field dissipation of four-pole sources. Main results. Analysis of noise radiation direction and intensity, physical interpretation of the processes taking place in this phenomenon, demonstration of the possibility to directly apply acoustic test data to various flow patterns. Conclusion. The results of this work could be used in acoustic design of silent hydraulic equipment. |
