Abstract
In the paper we study the impact of the boundary vorticity distribution on the dynamics of enstrophy for flows around streamlined bodies. A new energy identity is derived in the article, which includes the boundary values of the vortex function. For the Stokes system the dissipativity of enstrophy is proved. For the Navier–Stokes system a new equation of the enstrophy dynamics is obtained.
