【摘要】 在自然对流条件下,对含空气的蒸汽在波节管管外表面冷凝传热进行实验研究,给出了换热器内主流温度和波节管外壁面温度的分布,分析了波节管对含空气的蒸汽冷凝的影响,并与光管实验结果进行了对比。结果表明:波节管条件下,气体总压、空气含量和壁面过冷度等因素对冷凝传热系数的影响与光管情况类似;与光管相比,波节管冷凝传热系数略大于光管。更多还原

【Abstract】 In this study, steam-air condensation outside a vertical wave tube was conducted under free convection. Bulk temperature distribution and condenser tube outer surface temperature distribution were measured. The influence of wave tube on steam-air condensation has been studied, and the result was compared with that of smooth tube. The experiment shows that the effect of total pressure, air mass fraction and wall subcooling on the heat transfer coefficient for wave tube is similar to that for smooth tube. Compared with smooth tube, the wave tube enhances the steam-air condensation heat transfer process slightly.更多还原
