摘要
本文对三维内微肋管内进口区段R134a过热蒸汽的凝结换热过程进行了实验研究。结果表明；微肋管内过热蒸汽过热度降低的速率明显高于光管，且主要受质量流率和管望过冷度的影响.本文得到的过热蒸汽凝结换热计算式与实验的偏差在±15％以内。
An experimental investigation of R134a superheated vapor condensation in the entrance region of three-dimensional microfin tube is conducted. The decease rate of superheated vapor temperature in the 3-D microfin tube is larger than that in smooth tube.The obtained empirical correlation of superheated vapor condensation has ±15% deviationwhen compared with the experimental data.
