摘要
根据流动相似原则对梯形剖面肋片管的模型温度场沿肋高、肋厚的分布规律进行了实际测定,对环肋结构优化有重要参考作用。
In this paper,a new calculation method for the temperature distribution along the fin height of the annular-finned tube with trapezoidal cross-sectional profile was presented.The experimental data show that the calculation method has high accuracy,and meanwhile, the temperature distribution across the fin base was measured, the experimental data of the temperature distribution were useful for the construction optimization of the finned tube heat exchangers.
