Invariants for the onepoint vorticity and strain rate correlation functions
Abstract
An algorithm to enumerate the number of independent scalars that determine the general tensor formed from n velocity gradients at a point in homogeneousisotropic turbulence is elaborated for n = 4. The physical content of the invariants that result as well as their determination from experiment is discussed.
