Computational vortex dynamics in two and three dimensionsA discussion of some solutions and outstanding problems of dissipationless and nearly dissipationless flows in two and three dimensions is presented. In particular, two-dimensional steady-state solutions, linear stability and nonlinear evolutions including axisymmetrization of isolated vortex regions and merger or condensation of like-signed vorticity regions, are reviewed. These results are obtained from pseudo-spectral codes, contour dynamical (CD) codes and a new Hamiltonian moment-model of the Euler equations
