Deep learning of vortex-induced vibrations [PDF]

Journal of Fluid Mechanics, 2018
Vortex-induced vibrations of bluff bodies occur when the vortex shedding frequency is close to the natural frequency of the structure. Of interest is the prediction of the lift and drag forces on the structure given some limited and scattered information on the velocity field.
