Forces on a Horizontal Cylinder Due to Non-Linear Waves

Abstract

A horizontal cylinder, located near the floor of a two dimensional wave channel was subjected to a train of non-linear gravity waves. The horizontal and vertical forces were measured and presented in dimensionless form. Experimental values of horizontal and vertical force coefficients are presented as functions of dimensionless wave height and dimensionless wave period. The dimensionless force coefficients predicted by a modified Morrison equation and a Froude-Krilov force are compared to experimental data. Fluid particle velocity and acceleration values were calculated from Stokes fifth- order gravity wave theory. Experimental dimensionless wave periods from 10 to 200 were investigated.
