【摘要】 本文描述了缠丝管在纯R113和含油R113中的沸腾传热。选择了最佳的金属丝径和缠绕螺距。当q<50kW/m~2时,没有热滞后并优于GEWA-T管。含油时,所有的强化管传热性能会减弱。当q>10kW/m~2时,缠丝管性能稍有降低,油的影响不明显。更多还原

【Abstract】 This paper described the boiling heat transfer on the metal wire wrapped tube with the R113 and R113-oil mixtures. The optimum wire diameter and the wrapped screw pitch were chosen. There is no hysterisis and outperforms the GEWA-T tube when the q<50 kW/m~2. With the oil presence, all of the enhanced tube experienced a deterioration in the heat transfer performance. The wrapped tube showed small degradation when the q>10kW/m~2, the effect of the oil is not evident.更多还原
