自由表面随机涡方法（FSRVM，Yeung，2002）被应用于研究两种类型的强迫运动问题，并考虑了粘性的影响。本文考虑了潜体周期性摆动振荡，并与Yeung和Wu（1991）的涡扩散理论的结果进行了比较，后者忽略了Navier-Stokes方程的对流项。本文以一个实际的矩形柱体为例，研究其横摇惯性和阻尼特性。与最近的一些实验结果进行比较，以说明该理论的有效性和准确性。
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.
