Numerical Simulation of Vortices Motion in Presence of Solid Boundaries
The important role of coherent structures on the comprehension of turbulence has been emphasized, recently, by experimental and numerical studies. Interactions of these large structures at different scales among themselves and interactions with the random field of the small scales is the mechanism which make turbulence a field not completely known. In the present study a numerical simulation has been done to describe, how large structures behave in presence of bodies of different shape. Although the calculation is limited to 2-D flowfields, this is a first step to build a numerical simulation for 3-D flowfields.
