MAXIMUM WAVE FORCE ON A COMPOUND CYLINDER.

Abstract

In-line wave force on a compound cylinder has been measured by a sophisticated single component force balance in a 2m multiplied by 1m multiplied by 35m long wave flume. Only circular cylinders were used with the various combinations of diameters and heights ratios of the top and base cylinders, at various wave conditions. The range of diffraction parameters used was 0. 1 to 2. 5. The experimental results generally agree with the trend predicted by the analytical equations, however, the measured peak forces were found to be significantly lower than the theoretical predictions. A semi-empirical equation is also obtained to predict the maximum wave force on single as well as compound cylinders.
