Experimental investigation of wave produced second-order steady forces on a submerged circular cylinder

Abstract

Second-order steady wave forces on a restrained, submerged, circular cylinder are studies experimentally as a function of cylinder depth and wave frequency. The experimental results are compared to forces calculated from a linearized potential theory. It is found that in all cases the experimentally observed forces are higher - is some case by an order of magnitude - and are not attenuated with depth as rapidly as predicted by the theory.
