添加剂强化沸腾传热性能的综合评价及预测

Comprehensive evaluation and prediction about enhancement of boiling heat transfer with additives

用模糊数学的方法对添加剂强化沸腾传热的性能建立了评价及预测模型。对文献中及作者试验过的３７种添加剂强化沸腾传热的效果作了拟合评价，结果表明，有３３种添加剂的评价结果与实测结果相符合，准确率为８９．２％．此外，还对油酸钠和聚乙烯醇两种添加剂强化沸腾传热的能力作了预测，结果也与实测结果相吻合．

The model of evaluation and prediction about enhancement of boiling heat transferwith additives has been founded according to fuzzy fundamentals.Correlative appraisement wasdone with this model with regard to the effects of boiling heat transfer augmentation with 37kinds of additives which were tested by the authors and other researchers. The resuIts show thatthe evaluation of 33 kinds of additives is consistent with experiments,which means that theaccuracy of the model is about 89.2 percent.In addition,the prediction for the ability of boilingheat transfer enhancement with sodium oleate and polyethylene glycol was carried out too,and itis also in good agreement with correspondent experiments.
