CF/IL/axial motions, structural and geometric nonlinearities and nonlinearities associated with the hydrodynamic forces caused by uniform and linearly sheared flows.
capabilities of the model in replicating experimentally-observed phenomena are demonstrated, the importance of the axial oscillations and the geometric nonlinearities are examined and discussed and the model is validated with available experimental results.
The effect of structurally geometrical nonlinearities has often been disregarded.
geometric nonlinearities for realistic VIV predictions and capturing multi-mode interactions.
Figure 2.19 depicts spatial variation of the root-mean-square (RMS) amplitudes of a flexible cylinder when the geometric nonlinearities are considered (Figure 2.19 (a)) and when these nonlinearities are neglected (Figure 2.19 (b)).
