Research on Wind Wave Simulation Technology based on Potential Flow Theory

Abstract

The wave environment is the main service environment of surface aircraft in the process of surface duty. In order to comprehensively study the operating characteristics of aircraft under this condition, it is necessary to conduct research on wave parameter modeling methods and simulation technology based on different wave conditions. This paper adopts the three-dimensional potential theory and ball model to calculate the different wave cases. A high-precision numerical simulation method of complex sea conditions is formed by mastering the numerical wave-making technology of typical regular and irregular waves. The result shows that the regular simulation in this paper has a high precision that the wave height and period is in 1% error compared with theory. The calculation error of spectral peak and peak frequency of sea states at all levels are within ± 8%, and the simulation quality of irregular waves meets the calculation requirements.

Study on the Influence of Ballast Tank Position on the Hydrodynamic Performance of Offshore Wind Turbine

“…In addition, the existence of the basic structure of the floating fan will cause changes in the surrounding flow field [7], resulting in diffraction and reflection of the incident wave. Since the influence of fluid viscosity effect is relatively small, the potential flow theory [8], which takes uniform, inviscous, incompressible and irrotational ideal fluid as the research object, is usually used to approximate the fluid force flow field.…”
