Abstract

The main point of this Brief Communication is that the turbulent energy production is due to the compressing of material elements rather than stretching. This is understood in the sense that the positiveness of the turbulent energy production is due to the contribution of the term associated with the compressive (negative) eigenvalue/eigenvector of the mean strain.
