摘　　要：介绍了钛螺纹槽管传热及流动阻力的实验结果,并对结果进行了分析。根据大量实验数据,得到了计算对流换热系数、冷凝换热系数及阻力系数的经验关联式。实验结果表明,钛螺纹槽管是实现冷凝器小型化较为理想的强化管管型。The results of experimental investigation on heat transfer and fluid pre ssure drop of spirally fluted titanium-tubes for steam con densation are reported and analyzed.Based on a lot of experimental data,the empirical correlations of single-phase heat transfer coefficient,condensation heat transfer coeffic ient and pressure drop factors are given.The results of experiments showed that s pirally fluted titanium-tube are better choice on heat transfer enhancement for the miniaturization of naval ste am condensers.
