Research area

- numerical modelling of 2D and 3D vortex structures by „vortex in cell” (ViC) method

- discretization of vorticity field

Formulation of the problem in termsof vorticity and vector potential fields

Research area

-investigation of interaction of vortex ring with rigid wall

-analysis of vortex structures interactions in 2D and 3D inviscid and viscous flows

Page 4: Wroclaw University  of Technology Department of Numerical Modelling  of Flows

Possible areas of further investigations

- evolution of turbulent spots in boundary layer,

- investigation of interaction of vortex rings with a wall and study of creation and evolution of secondary vortex structures,

- investigation of evolution of a set of vortex structures in 3D flow,

-Implementation to the algorithm a model of turbulence
