On azimuthal wave-induced distortion of variable density swirling flows across non-linear critical layers
A non-linear critical layer analysis of the presence of singular azimuthal neutral modes in density stratified swirling flows is considered. It is shown that finite amplitude neutral modes exist when the basic flow velocity, vorticity, and temperature profiles undergo distortions with the occurrence of jump in them.
