Convergence in axisymmetric flows speeded. Improved treatment devised for swirl-coupling source terms in finite-difference Navier-Stokes calculations of axisymmetric flow. Essence of improvement to treat radial- and swirl-velocity source terms in implicit manner wherever possible. Results in faster convergence and in convergence in some cases in which explicit treatment does not yield convergence at all.
