Modelling VIV of Transversally Oscillating Rigid Structures Using Nonlinear Fluid Oscillators

Abstract:

This work is aimed to develop a series of wake oscillator models to pbkp_redict displacements of the single degree-of-freedom (1DOF) rigid structure for a range of mass ratio. The work includes modification of the model with alternative damping terms, calibration of the models with the "medium" mass ratio (around 6.0), validation with the same experimental arrangement, validation with the different set-up and definition of the application range.
