摘要
采用一个具体的实例对比分析了当前最为常用的几种自由面确定方法 ,阐明了各自的优缺点 ;然后在此基础上对单元传导矩阵调整法作了简化和改进 ,提出了等效渗透系数法。应用表明 ,等效渗透系数法不仅具有足够的计算精度 ,而且还具备算法简单。
Based on a sample, the most commonly used methods that can search the surface of unconfined flow were analyzed. The Elemental Conducting Matrix Adjustment Method was simplified and improved, and the Equivalent Penetration Coefficient Method was proposed. It is concluded that the Equivalent Penetration Coefficient Method is accurate, simple, and easy to be popularized.
