Query: The energy cascade at the turbulent/non-turbulent interface   Interscale energy transfers at the vicinity of the turbulent/non-turbulent
interface are from small to large scales in directions close to the interface's
tangent plane where motions are predominantly stretching, but from large to
small scales in the other directions where motions are predominantly
compressive and significantly correlated with square angular momentum. An
important role in this predominance is played by the extreme compressive
motions which can be significantly more likely than extreme stretching motions
even where motions are on average stretching. The most intense interscale
transfer rates and dissipation occur when the interface is as far as possible
from the wake centreline.
