Fundamental and subharmonic transition to turbulence in zero-pressure-gradient flat-plate boundary layers

摘要

In this fluid dynamics video, recent simulations of transition to turbulencein compressible (M = 0.2), zero-pressure-gradient flat-plate boundary layerstriggered by fundamental (Klebanoff K-type) and subharmonic (Herbert H-type)secondary instabilities of Tollmien-Schlichting waves are highlighted.
