Modelling of coupled cross-flow/in-line vortex-induced vibrations using double Duffing and van der Pol oscillators [PDF]
, 2012 Many studies have typically applied a linear structural spring–mass–damper oscillator and a van der Pol wake oscillator to model a one-dimensional cross-flow vortex-induced vibration (VIV).

Numerical Simulation on Vortex Shedding from a Hydrofoil in Steady Flow
Journal of Marine Science and Engineering, 2020 This paper presents a numerical modeling procedure for the idealization of vortex shedding effects in the wake flow field of a NACA0009 hydrofoil. During the simulation, the lift and drag acting on the hydrofoil were monitored, and the vortex-shedding ...
