Superresonant instability of a compressible hydrodynamic vortex
Research output: Contribution to journal › Journal article › Research › peer-review
We show that a purely circulating and compressible system, in an adiabatic regime of acoustic propagation, presents superresonant instabilities. To show the existence these instabilities, we compute the quasinormal mode frequencies of this system numerically using two different frequency domain methods.
