A new Particle Vortex Method, called Diffused Vortex Hydrodynamics (DVH), has been recently developed at CNR-INSEAN. This method presents some similarities with the SPH linked to its meshless nature even if it is based on a different numerical approach. In this work advantages and drawbacks are highlighted by testing these particle methods on selected test-cases and by performing heuristic convergence measurements. We underline that the present work is not aimed at comparing DVH and SPH in terms of abilities in solving specific fluid-dynamic problems, but rather at showing the similarities of these two different particle methods. Indeed, the performed analysis shows similar behaviours on the convergence of the two schemes.

Abstract
A new Particle Vortex Method, called Diffused Vortex Hydrodynamics (DVH), has been recently developed at CNR-INSEAN. This method presents some similarities with the SPH linked to its meshless nature even if it is based on a different numerical approach. In this work advantages and drawbacks are highlighted by testing these particle methods on selected test-cases and by performing heuristic convergence measurements. We underline that the present work is not aimed at comparing DVH and SPH in terms of abilities in solving specific fluid-dynamic problems, but rather at showing the similarities of these two different particle methods. Indeed, the performed analysis shows similar behaviours on the convergence of the two schemes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
