Аннотация
The paper continues investigations of a fundamental problem important for understanding the nature of vortex flows: sound radiation by a perturbed Rankine vortex. Results of numerical simulation are presented for both quadrupole and higher-mode radiations. The structure and dynamics of tonal acoustic radiation generated by a vortex are considered in detail. The transition of a Rankine vortex to a perturbed state under small external perturbation is considered. Calculations are performed using the EBR scheme implemented by NOISEtte software.
