Formation of Kármán Vortex Street in RWIND Simulation

Is it possible to design a "Kármán vortex street" behind an object in the numerical wind tunnel of RWIND Simulation?


Answer:

Yes, the effect of a "Kármán vortex street" can be modeled in RWIND2 with the "Transient Flow" mode; this was not possible in previous versions.

Narrow and tall models, in particular, require extremely fine meshing over the entire height. Furthermore, the effect is heavily dependent on the Reynolds number and surface roughness settings.

Under Links, you can find a suitable model as an example in [1], as well as a visualization in [2] , and the corresponding documentation in [3] .
