THE NUMERICAL WIND TUNNEL

Palestrante: Dr. Julio Militzer, "Dalhousie University", Canadá.

Ementa da Palestra

The Numerical Wind Tunnel is a 3D Computational Fluid Dynamics program. Some of its features are:

• Immersed Boundary Method (IBM) for boundary condition specification, which allows easy simulation of moving objects.
• Anisotropic Cartesian mesh with automatic grid refinement/coarsening (based on inter cell velocity gradients).
• Parallelized code running on PC clusters and supercomputers, with dynamic domain decomposition and automatic cell redistribution.
• Multi scale Large Eddy Simulation turbulence model.

The code has been used to simulate the flow around long cylindrical petroleum exploration risers subjected to vortex induced vibrations. Results of these simulations will also be presented. The documentation is being prepared to release the Numerical Wind Tunnel as "free ware".
