简单计数算法（SCA）的体积跟踪模拟的停滞液体中的单个气泡的有效性进行了检查。结果表明，SCA能保持尖锐的界面，但气泡体积增大。为了减小体积误差，提出了一种改进的SCA。本文对单个气泡在静水中的上升过程进行了数值模拟，采用的是一种粗网格，即气泡当量直径只有6个单元。气泡体积保持良好，清晰的界面保持时间长达12秒。
The validity of the Simple Counting Algorithm (SCA) for the volume tracking simulations of a single bubble in stagnant liquid is examined. As a result, it is confirmed that ( i ) the SCA can keep sharp interface, but (ii) the volume of bubble is increased. An improved SCA is proposed in order to reduce the volume error. Numerical simulations of a single air bubble rising in stagnant water are carried out using a course grid, i.e. only 6 cells to the bubble equivalent diameter. The volume of bubble is conserved well and a sharp interface is kept for as long as 12 seconds.
