Palinstrophy is the curl of the vorticity. It is defined as where is the vorticity. Palinstrophy is mainly used in turbulence study, where there is a need to quantify how vorticity is transferred from one direction to the others. It is closely related to enstrophy, the latter being more equivalent to the "power" of vorticity. ==References== *Lesieur, Marcel. "Turbulence in fluids: stochastic and numerical modeling."
