Abstract:

We develop grid-free numerical procedures to compute axisymmetric incompressible flows. In particular, we formulate a grid-free `redistribution method' to handle diffusion processes accurately on a disordered collection of computational elements. We validate the numerical procedures by computing the Stokes flow and the Navier-Stokes flow of a vortex ring.
