The Free-Surface Random-Vortex Method (FSRVM, Yeung, 2002) is applied to investigate two types of forced motion problems with the effects of viscosity considered. A submerged body undergoing periodic swaying oscillation is considered and compared with the results of the vorticity-diffusion theory of Yeung and Wu (1991), which had the convective terms of the Navier-Stokes equations neglected. A practical shape consisting of a rectangular cylinder with horizontal and vertical keels or baffle-plates is used to study the roll inertia and damping characteristics. Comparison is made with some recent experimental results to illustrate the efficacy and accuracy of the theory.
