Abstract
The objective of this work to develop a fast and effective in situ sensing and control method for flexible hydrodynamic lifting bodies in complex, multiphase flows. The sensing system is based on embedded strain and accelerometer measurements, which were used to reconstruct the real-time in situ 3-D deformations and off-line modal characteristics of a flexible surface-piercing hydrofoil in multiphase flow. An inverse fluid-structure interaction solver is used to determine the unknown operating conditions, hydrodynamic load distributions, cavitation and ventilation patterns. Good agreements are observed between predictions and measurements. Finally, preliminary experimental results are shown for a new ventilation control method that takes advantage of the measured in situ modal characteristics.
