Abstract

This paper deal with the time history of liquid surface wave motion in a rectangular tank which is oscillated horizontally. In theoretical analysis, the governing equations of liquid surface wave motion are derived by applying the variational principle. The nonlinear ordinary differential equations of time which govern liquid surface wave motion are derived by using Dirichlet-Neumann operators. An experiment was carried out using a model tank. The frequency components are observed by applying the discrete Fourier Transform to the theoretical results and the experimental results. The high-frequency components are observed at the both results. And, these results are in good agreement qualitatively.
