该文介绍了汽水混合物在φ６０ｍｍ×７ｍｍ矩型槽内螺纹管内流动时，当压力为１９．６ＭＰａ、不同热负荷和重量流速下所进行的传热性能试验结果，得出在此压力下矩型槽内螺纹管传热恶化时临界合汽率的计算公式．试验研究表明：矩型槽内螺纹管可推迟传热恶化的发生。图７表１参１
This paper introduces the test results of heat transfer performance of steam-water mixture flowing in a φ60mm × 7mm rectangular grooved screw tube under the condition of pressure 19.6MPa, different heat load and weight flow rate. It is concluded that under this pressure, Calculation formula of critical combined steam rate when heat transfer in grooved pipe is deteriorated. Experimental studies show that: Rectangular grooved tube can delay the deterioration of heat transfer. Figure 7 Table 1 Reference 1
