The flow structures for the most general cases, as well as, the limiting three-dimensional cases are established using scaling analysis. The boundary in the limiting three-dimensional case where the flow is started to be perturbed is analysed using a self-similar technique. The solution is then presented using Fourier mode waves, while their initial phases are determined in a linearised approximated model. For the typical structure in which self-similar method is pursued, the displacement e ffect which plays an important role in doing the full criss-cross interaction is ineff ective, instead, the influence of disturbance is mainly a ected by centrifugal forces. The result being that the full perturbation equations degenerate into three independent ordinary di erential equations which can be solved analytically.
