27 de jun. de 2024 · The calculation method of wave power density (Pw) is a key link in the research of wave energy. The most representative studies in China include the climatological method adopted by Ma and Yu ( 1983 ) and the method of real weather chart data of the Yellow Sea and Bohai Sea surfaces adopted by Li et al. ( 1984 ), which are also well-known studies on the calculation of wave power density in China.
