The galloping of a 4:1 rectangular cylinder at Re = 300

open access: yesAIP Advances, 2023
The flow-induced vibration (FIV) of a rectangular cylinder with a side ratio of 4 at Re = 300 is numerically investigated by a two-dimensional spectral-element method. The cylinder is constrained to vibrate only in the cross-flow direction.
