This paper presents a two-dimensional implementation of the high-order penalized vortex in cell method applied to solve the flow past an airfoil with a vortex trapping cavity operating under moderate Reynolds number. The purpose of this article is to

In this paper, the motion of the n-vortex system as it collapses to a point in finite time is studied. The motion of vortices is described by the set of ordinary differential equations that we are able to solve analytically. The explicit formula for

The vortex particle method is an easy and attractive tool to analyze flow phenomena by investigating vorticity fields and the generation of vorticity at solid walls. The vorticity generation at the walls and its introduction to the flow is of fundame

In the paper the vortex in cell method for the simulation of the viscous flow in a complex geometry was described. Vorticity field is approximated by the collection of the particles that carries the circulation. The local velocity of a particle was o

The system of n-point vortices that are in a self-similar motion can collapse to the point in a finite time. An explicit solution for such collapsing trajectories system was derived. The numerical evidence was presented that collapse vortices may org

A system of a finite number of linear vortices in self-similar motion and under suitable conditions that are related to the initial positions and circulations of the vortices can collapse to the point with finite time. It is shown how the initial pos

Parallel implementation of the Vortex-in-Cell (VIC) method for 3D flow on many graphics cards was presented. As test problems it was chosen the leapfrogging and head-on collision of two vortex rings for which a well documented visualization exists in

To avoid a large consumption of computer time instead of the direct vortex methods with Biot-Savart interaction law, the vortex in cell method was used. The local velocity of a particle was obtained by the solution of the Poisson equation for the str
