  • Sunroof Buffeting Vorticity Simulation A simulation of sunroof buffeting I did as part of my Fluid Mechanics coursework. Buffeting is what we call those annoying pressure variations that happen in a lot of cars if you open one of the windows (or the sunroof) and drive at a relatively low speed. It can get very annoying very quickly, so it's one of the things that auto makers try to reduce. That's what the little pop-up deflector thing at the edge of the sunroof is for, usually. Vorticity is a measure of how much air is spinning around. This lets us see where the vortices are forming so we can come up with things to do to screw up their formation.

  • Sunroof Buffeting Vorticity Simulation, With Bar A simulation of sunroof buffeting I did as part of my Fluid Mechanics coursework. Buffeting is what we call those annoying pressure variations that happen in a lot of cars if you open one of the windows (or the sunroof) and drive at a relatively low speed. It can get very annoying very quickly, so it's one of the things that auto makers try to reduce. That's what the little pop-up deflector thing at the edge of the sunroof is for, usually. Vorticity is a measure of how much air is spinning around. This lets us see where the vortices are forming so we can come up with things to do to screw up their formation. In this case, my team stuck a bar in the sunroof opening. This helps to break up the vortices before they get too strong and break the coupling between the resonant frequency of the cabin and the shedding frequency of the vortices off of the roof.

We combined a particle system with multiple Eulerian grids to reproduce the multi-level vorticity efficiently.

  • Vorticity for Hybrido Tutorial Hi everyone.. :) As you know there is no way to calculate vorticity in realflow "hybrido solver" (realflow Grid based simulation) even though "vorticity" gives us an excellent option to create an imitation of foam activity in water collision areas by rendering with Krakatoa KCM etc. So somehow I got an idea how to do it, and it just worked ..! I hope that is clear and understandable tutorial I'm pretty sure you do not want to hear my broken English .. Or that the tutorial will be in Hebrew :) Anyway .. Enjoy.. :)

  • Vorticity - Mixing Layer The simulation considers a temporal developing mixing layer. The initial horizontal velocity has a hyperbolic-tangent profile. From linear stability ***ysis the mixing layer is known to be invisicidly unstable. A perturbation leads to the formation of vortices by KelvinHelmholtz instability. KelvinHelmholtz instability leads to the development of vortices which in a later stage roll-up and merge.
