| 中文摘要: |
| 使用有限元方法对横掠不同型式措排光滑管束进行了计算分析，绘制了速度场和温度场的色差梯度图，比较了它们的传热与流动性能。有限元分析方法作为热分析和流动分析研究的有力工具，可以与实验研究相结合作为研究管束传热与流动性能的一种新方法。研究结果对于横掠光滑管束的优化设计具有一定的指导意义。 |
| 英文摘要: |
| Numerical investigations on heat transfer and fluid flow over different banks of staggered smooth tubes were carried out in this work using the finite element method. Pictures of chromatism gradient of the velocity and temperature fields for different tube banks were made, and their heat transfer and flow characteristics were compared and analyzed. The finite element method is thus an effective technique for investigating heat transfer and flow characteristics of tube banks in combination with experiments. This work is instructive to the optimization design of smooth tube banks. |
