Need help finding the name of a fluid mechanics/frequency graph

[rcummings89]

Someone showed me a graph that has to do with how a cylinder oscillates in uniform flow, starting from no oscillation, to high oscillation, back to none. I know the y-axis is amplitude/diameter and the x-axis is velocity / (natural frequency X diameter)

I would just like to find out more information but I don't know where to look. Any help is greatly appreciated!

Try a google search for "flow around oscillating cylinder" ;)

That may give you the results you want. I suspect you'll find the root phenomenon faster though if you search for "Karman Vortex Street"

Searching Strouhal number may also be of interest.

The graph you are describing is likely a vortex shedding frequency graph. This type of graph shows the relationship between the velocity of a fluid and the frequency at which vortices are shed from a cylinder placed in the flow. As the velocity increases, the frequency of vortex shedding also increases until it reaches a critical point, after which the vortices are no longer shed and the cylinder experiences no oscillation. This phenomenon is important in fluid mechanics and is often studied in applications such as aerodynamics and structural engineering. You can find more information about vortex shedding and its applications by searching for "vortex shedding frequency" or "Karman vortex street" in scientific literature or online resources.
