Stability of variable density rotating flows: Inviscid case and viscous effects in the limit of large Reynolds numbers

Autor: Jacques, C., Di Pierro, B., Alizard, F., Buffat, M., Cadiou, A., Penven, L. Le

Publikováno v: Physical Review Fluids, 2023, 8 (3), pp.033901

Linear stability of solid body rotating flows with axisymmetric density variations is addressed analytically. Considering inviscid disturbances, a non trivial dispersion relation is obtained and it is shown that the instability is of Rayleigh-Taylor
