ON THE VARIATION OF CHARACTERISTICS OF TWO WAVE TRAINS CROSSING IN INTERMEDIATE DEPTH

In this paper , the authors paid attention to the non- linear interaction of two free wave trains crossing in intermediate water depth. From theoretical approaches , the velocity potential and water surface elevation have been expanded to the second-order by perturbation method. And wave height , velocity of fluid particles , pressure distribution , wave thrust and energy density of the common wave are also investigated. In order to verify the theoretical results , elaborated and numerous experiments have been performed. Some of the remarkable coincidence are obtained and the conclusions have been presented in this paper.
