摘要:
为了探索卧式螺旋管内流动沸腾传热恶化特性及预测准则,进行了以R134a为工质的实验研究.实验结果表明:在高干度区,低质量流速时一般内侧壁温先飞升,外侧壁温后飞升,但起飞点的间距较小,且飞升点在干度为0.73附近;高质量流速时,内、外侧壁温几乎同时飞升,飞升点发生在干度为0.78附近.进一步分析了临界热流密度与干度的关系及热流密度对平均传热系数的影响.根据实验结果,拟合出了适用于卧式螺旋管内流动沸腾传热恶化发生时的预测模型,经实验验证,预测值与实验值吻合较好.
Abstract:
An investigation was experimentally carried out with R134a to explore flow boiling heat transfer deterioration characteristics and its prediction criterion in horizontal helically-coiled tubes. The results show that in high quality area, the inside wall temperature soars generally and then the outer wall temperature rises in low mass flow rate; but their take-off point spacing is small and rising point is about the quality of 0.73. The inside and outside wall temperature soars nearly simultaneously in high mass flow rate, and rising point is about the quality of 0.78. The relationship between the critical heat flux and the quality and the influence of heat flux on the average heat transfer coefficient are analyzed. Based on the experimental results, the prediction model of heat transfer deterioration for flow boiling heat transfer in the horizontal helically-coiled tube is developed. It is verified that the predicted values are in agreement with the experimental values.
