On the solenoidality of the Lamb vector

Research output: Contribution to journalArticlepeer-review

Abstract

The correlation between reduction of the nonlinearity and other characteristic quantities of turbulent flow is investigated numerically. It is shown in physical space that in the regions exhibiting strong depletion of nonlinearity, the enstrophy and the enstrophy production are large. In the same regions vorticity has a tendency to be perpendicular to the eigenvector of rate of strain corresponding to the smallest eigenvalue. No correlation has been found between reduction of nonlinearity and dissipation.
