The hydrodynamic model of electron transport is revisited. By rearranging the governing equations a new set of equations in terms of the electron vorticity and internal energy is derived. The advantage of the new set of equations is the explicit removal of the electric field from the equations. A scale analysis of the electron vorticity equation is performed and the conditions for the observation of electron vortices in high field transport in sub-micron devices are predicted.
