Hello Stressers!!
I know this is not a Caesar II related question. Just curious if someone have tried in CFD calculation the amplification of turbulent eddy (vortex) (which has a certain frequency of vortex generation) due to high velocity flow in discontinuities (such as valves, elbows, tees, etc.) in which it couples to the acoustic mode of the fluid (open-open or open-close boundary condition).
I cannot find any example in CFD software in how to solve this. What I have found in some technical articles is the amplification is in the order of 2 to 4. And if I was not mistaken in what I have read is that it can be measured experimentally.
I'm not sure if this can be treated like a harmonic type of analysis (amplification due to strong coupling or resonance.)
Many Thanks & Cheers!!!
