Abstract:

In view of different wave height and period in the South China Sea, the design of Wave Glider wing parameters is studied to obtain greater thrust. Based on the reanalysis data set of ERA5, we provide statistics on the wave height and wave period of different seasons and induced by one typhoon in the South China Sea. In addition, the software FLUENT is used to study the influence of the maximum limit angle, the position of rotating axis and the spacing of the wings. The simulation results show that the larger the wave height, the larger the maximum limit angle should be in order to ensure that the wings can get more thrust. Under the conditions of wave height and period in the South China Sea, it is better to select 1/5 of the front of the wing as the position of rotating axis. Increasing the spacing of the wings properly can improve the thrust. By simulating the flapping wings, the thrust generated by the wings under different parameters is obtained, which provides a reference for the design of the wings.

Key words: Wave Glider, maximum limit angle, position of rotating axis, spacing of the wings
