ABSTRACT

The purpose of this research is to investigate the flow field of pitching hydrofoils of different geometries in the water tunnel, and examine the corresponding forces and moments for pitching motion. This is to enable us to find the suitable hydrofoil geometry to be used for swimming or flapping applications. In order to understand how different hydrofoil geometries affect the various forces acting on it, experiments are conducted to study the hydrodynamic force and flow field around a pitching hydrofoil. In addition, the findings are enhanced by using the dye flow visualizations, PIV analyses, and the CFD simulation. The experiments are conducted on both the symmetrical and asymmetrical hydrofoils such as the symmetrical SD8020, and asymmetrical CH10SM, M06-13-128, and NACA 2414. Among the four hydrofoils investigated, we conclude that symmetrical SD8020 hydrofoil performs the best, followed by asymmetrical M06-13-128 hydrofoil, then asymmetrical CH10SM and NACA 2414 hydrofoils.
