摘要
Breakdown process of the Klebanoff mode and origin of turbulence are experimentally investigated in detail. An acoustic excitation using a 2D roughness attached on the wall are used for T-S wave generation. Piezo-ceramic actuators are used to introduce the Klebanoff mode fluctuation. It is shown that the turbulence region starts from two locations, one is beneath the head of a A vortex and the other is the high-shear layer accompanying by the A vortex.
