By Hao Quan and Gregory Eyink

The Josephson-Anderson relation, valid for the incompressible Navier-Stokes solutions which describe flow around a solid body, instantaneously equates the power dissipated by drag to the flux of vorticity across the flow lines of the potential Euler solution considered by d'Alembert. Its derivation involves a decomposition of the velocity field into... Show more
