Abstract

Abstract

The secondary instability theory is used to study the behavior of spatially growing disturbance in free turbulent shear layer.The numerical results indicate that secondary instability of subharmonic mode shows a strong choice of spanwise wavenumber andthe maximum growth two dimensional case.In contrast to that secondary instabilities of the fundamental mode occur in a wide scope of spanwise wavenumber.We have found so called translative at β=0 and bifurcation phenomenon for an amplitude of the KH wave larger than 0.06.
