Statistical properties of fluid motion and fluid force in a random wave field
Abstract
Preliminary studies of the effects of the free surface fluctuations on the statistical properties of wave field kinematics, pressure, and wave force were carried out. It is the purpose of this study to extend the idea developed by Tung to further derive the probability density function, mean, variance, skewness, covariance function, and spectrum of the horizontal components of fluid particle velocity, acceleration, pressure, and wave force. Numerical results are obtained for a mean wind velocity of w = 40 mph, presented graphically, and compared with those obtained previously in which the free surface fluctuation phenomenon was ignored.
