| 摘 要： | 本文从实验的角度出发,对正弦型剖面的纵槽管进行了研究。找出了局部换热量与纵向坐标的关系。在拟合准则方程时,文中引进了一个新的特征参数L_c。并以此得到无量纲纵坐标z/L_c替代其他学者用实验段管长L来得到无量纲纵坐标z/L。且指出了原方法的不足之处。

| Abstract: | An experiment study of heat transfer through condensation in vertical sine-shape fluted tube is made. The relationship of the local heat transfer and the vertical coordinate is discerned. When we derive the practical relationship, a new characteristic constant L_c is proposed. Then we use the L_c to display the new dimensionless vertical coordinate (z/L_c) to replace the original dimensionless vertical coodinate (z/L) obtained through the tube length used by other researchers. |
