APPLICABILITY STUDY OF QUASI-DETERMINISM THEORY OF LARGE WAVES NEAR ZHEJIANG COAST
Accurate characterization of the large wave shapes is vital for efficiency and load calculations of wave energy converters.Meanwhile,conditional probability-based quasi-determinism theory offers a way to access it.Using 3-day wave measurement data collected offshore of Wenling,Zhejiang Province during Typhoon Ampil's transit in 2018,the measured average shapes of large waves and corresponding quasi-determinism waves are calculated by a self-programmed code.Then,the applicability of quasi-determinism theory for accurately characterizing these large wave shapes is discussed.The results show that the overall accuracy of the calculation is good;the larger the spectral peakedness of the spectrum(the narrower the spectrum),the higher accuracy of the quasi-determinism theory,and the correlation coefficient reaches-0.56;the correlation coefficient between wave steepness and quasi-determinism theory accuracy is 0.36;the Gaussianity of the sea state has no substantial relationship with quasi-determinism theory accuracy.
