Energy cascade at the turbulent/nonturbulent interface
Y. Zhou, J. C. Vassilicos
Abstract
Interscale energy transfers at the turbulent/non-turbulent interface are from small to large scales near the interface's tangent plane where motions are predominantly stretching, but from large to small scales in other directions where motions are predominantly compressive. This predominance is partly due to extreme compressive motions which can be significantly more likely than extreme stretching motions even where motions are on average stretching.
