Question:
Is it possible to design a "Kármán vortex street" behind an object in the numerical wind tunnel of RWIND Simulation?
Answer:
In the RWIND Simulation program, a stationary flow analysis of incompressible gases is implemented. The principles and formulations used for this do not change over time. Thus, the calculation gives a result set without temporal variation.
[1] The effect of a "Kármán vortex street", in which counter-rotating vortices develop behind a body around which there is flow, results in a temporal change of the flow effect. Therefore, this fluid-mechanical effect cannot be simulated in RWIND Simulation.
