Presentationtitle: Optimization of Flapping Foil Motion in Ship Propulsion for Maximum Thrust Augmentation

A state-of-the-art application for thrust augmentation in ship propulsion based on biomimetics is the flapping hydrofoil system, where the foil is subjected in a combination of two periodic (sinusoidal) motions, namely a heaving motion and a pitching motion with a phase lag between them. In this work, the amplitude and frequency of the heaving and pitching motions and the phase lag are considered as key parameters. Parametric studies are performed in order to explore the trends of the flapping foil performance and useful conclusions are drawn. Furthermore, a static optimization problem is defined and solved in order to seek the values of the motion parameters that optimize propulsion efficiency. The optimal solution yields very low thrust, dictating that rather suitable multi-objective problems have to be solved in order to obtain practical and profitable solutions.
