Discussion of wave behavior for improvement of spar type offshore wind power plant by particle method

Abstract

Spar-type offshore wind power generation is a kind of floating wind power generation facilities that, unlike fixed wind turbines, is installed in deep sea water. One of its characteristics is that it is not easily affected by waves. However, in order to ensure stability and safety, it is necessary to conduct analysis using appropriate simulation techniques. In this study, the δ-SPH method, one of particle methods, was used to analyze the wave behavior of two new types of spar-type offshore wind power generation. In the present paper, we studied the changes in wave behavior when the values of the modified artificial viscosity term and the artificial density-diffusion term introduced into the δ-SPH method are varied.
