Nononedimensional and selfsimilar properties of explosive processes in stratified shear flows
Abstract
Explosive interactions of zeroenergy waves in stratified shear flows are analyzed in the context of threedimensional geometry (twodimensional interaction in a horizontal plane of waves with a mode structure along the vertical coordinate). It is shown that explosive interaction of zeroenergy waves in stratified shear flows occurs every time the flow stabilty parameter exceeds a certain threshold level. With the exception of degenerate case, such an interaction is shown to lead to an explosive rise of threedimensional perturbations during the subharmonic decomposition of the initially twodimensional zeroenergy wave.
