| 摘要: |
| 运用信息保存法对低速圆管的流动现象进行了模拟，并与实验结果进行了比较，粒子仿真结果与实验结果吻合较好，且优于NS方程的结果。研究表明，在对低速圆管的模拟过程中，运用IP法在获得较好的结果的同时，具有比DSMC方法更高的计算效率。IP算法是解决低速圆管流动问题的有效途径。 |

| Abstract: |
| The information preservation method (IP) is applied to calculate the low-speed flow in a tube. The results are compared with that of the experiment and the datum tallies well. The results of IP method is better than NS equations'. The study indicates that IP method is an effective method to simulate the low-speed flow in a tube. Furthermore, better results and higher computer efficiency can be achieved. |
