| 摘 要： | 对水平螺旋管外开有Ｖ型槽时的凝结换热强化问题进行了理论研究．针对Ｖ型槽的冷凝换热特点，将Ｖ型槽流动区域分为传热区和液流区两个部分，对其分别建立了理论模型，并进行了数学描写．通过分析两个区之间流动和换热的有机联系，得到了螺旋管外Ｖ型槽冷凝换热问题的理论解，并给出了能用于工程实际的换热准则方程式．

| Abstract: | Investigation is made for enhanced condensation outside the horizontal coil tubes with V grooves. According to the flow and heat transfer characteristics of grooves, modeling of heat transfer and condensate flow area are developed. A correlation is proposed for the condensation heat transfer outside coil tube with V grooves. The result compares well with experimental data. |
