Figure 8
From: An inertial mechanism behind dynamic station holding by fish swinging in a vortex street
Histogram of extracted fish muscle curvature phase versus non-dimensional distance to vortex. \(\lambda\) denotes the distance between vortices, while the distance of the fish centre of volume to the next upstream vortex is \(x_{v}\). The extracted phase can been seen to vary close to linearly with distance to vortex. The figure shows data acquired from fish #1 swinging with a foil oscillation frequency of 2 Hz.
