Comparative Analysis of Hydrodynamic Performance of Small Wave Buoys

Abstract

Abstract The hydrodynamic performance of the floating body in seawater is very important. The wave buoy is a small buoy that measures wave parameters such as wave height and wave direction, for the non-powered wave buoy, the hydrodynamic performance mainly refers to the seaworthiness of the buoy body. Seakeeping refers to the motion law of the floating body in the wave. For the wave buoy, the seakeeping of the floating body has an important impact on the measurement of wave data. Therefore, the analysis of the hydrodynamic performance of the wave measurement float is an important reference for evaluating the performance of the wave buoy. In this paper, the hydrodynamic performance of cylindrical and spherical wave-finding buoys is compared and analyzed, and the influence of different structural forms on their hydrodynamic performance is analyzed, which provides a reference for optimizing the hydrodynamic performance of wave-measuring buoys.
