First European Workshop on Turbulence in Cryogenic Helium, CERN, Geneva, 23-25.04.2007
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
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
