| 摘 要： | 分析了有限元/控制体积方法和流动分析网络技术两种算法的区别,结果表明:在三角形网格上两种算法是一致的,在矩形网格上流动分析网络技术(FAN)相对于传统的有限元/控制体积方法(FE/CVM)可以构造更精确的控制体积表面流率计算方案。算例研究表明:对于矩形网格流动分析网络技术预测的填充时间精度比传统的有限元/控制体积方法提高几倍左右。

| Abstract: | The differences between the finite element/control volume method(FE/CVM) and the algorithm of flow analysis network(FAN) technology were analyzed. The results show that the two algorithms based on the triangular grid are uniform and the flow analysis network technology can construct more accurate schemes to calculate the flow rate through the control volume surface in comparison with the conventional finite element/control volume method. Numerical examples show that the accuracy predicted by the flow analysis network technology is several times higher than that predicted by the conventional finite element/control volume method. |
