摘要
以强化传热性能评价准则 （Ｎｕ／Ｎｕｓ） ／ （ｆ／ｆｓ）１３ 为基础， 在考虑污垢的条件下， 对纵向翅片管的强化传热性能进行了评价。结果表明， 与不考虑污垢的情况相比， 两者的评价结果有明显差异。本文的有关结果为工程上强化传热性能的评价提供参考。
Based on the evaluation criterion of enhanced heat transfer performance——(Nu/Nu s)/(f/fs) 1/3 ,the enhanced heat transfer performance on longitudinal finned tube is evaluated on the condition of accounting for the effect of fouling.The results show that there is distinct difference whether fouling is considered.The conclusions from this paper provide the reference for evaluation of enhanced heat transfer performance in engineering.
