Abstract

Abstract: The present paper provides an approximate method for the determination of velocity potential of nonlinear wave field by means of deformation about wave flow pattern on water surface particles. The method is based on Rienecker and Fenton's numerical wave theory.A program has been made according to the method. A photograph of typical wave flow visualization has been quantatively analysed. The calculated wave surface profile and velocities are compared with experimental ones and show a good agreement.

Key words: flow visualization, wave flow pattern, numerical wave theory, wave, particle velocity

摘要： 本文叙述利用实测流谱图中的波面信息,拟合求解Pienecker和Fenton的数值计算波中的傅立叶系数,从而建立该波动场势函数的方法。根据该法编制的计算机程序,处理了一张典型的浅水波场流谱图。对波面和质点速度的实测值、拟合值及二阶斯托克斯波的理论计算值间进行了比较,结果表明,实测值和拟合值间的一致性是好的。
