螺旋翅片管的换热计算

Numerical study on heat transfer in a spiral fin

本文引入区域平均表面传热系数的概念 ,在实验研究的基础上进行了肋基和肋端温度分布预测及肋片换热数值计算。

Based on the experimental studies of the natural convection resulting from heat transfer in a spiral finned tube, the numerical calculation was conducted, the average surface heat transfer coefficient for convection was defined and calculated, which has improved the computed temperature and fin efficiency.
