Forbes&Schwartz(1982)先前关于流体在水下半圆形扰动上的重力流动的研究被推广到包括表面张力的影响。给出了一个线性化理论，其中预测了解的三个不同分支的存在。用边界积分技术对完全非线性问题的求解支持了这一预测。对于线性化理论和非线性理论，计算了障碍物所经历的波阻。
A previous study by Forbes & Schwartz (1982) on flow under gravity of a fluid over a submerged semicircular disturbance is generalized to include the effects of surface tension. A linearized theory is presented, in which the existence of three different branches of solution is predicted. The solution of the fully nonlinear problem by a boundary-integral technique supports this prediction. The wave resistance experienced by the obstacle is computed for the linearized and nonlinear theories.
