与聚合物添加剂相比,表面活性剂减阻剂具有寿命长不发生降解的特点,已被广泛地应用到集中供暖(冷)系统.表面活性剂在降低流体湍流摩擦阻力时,溶液的传热性能恶化.为了扩大表面活性剂在传热领域的应用,理解传热下降的原因,针对表面活性剂溶液的湍流传热结构目前开展了一些实验研究和理论分析,但仅处于探索阶段、尚未定论.为了进一步开展研究,对目前国内外关于湍流传热结构的研究,以及取得的成果做了分析和总结,并分析了目前研究存在的问题,对今后继续开展研究提出了自己的观点.

The drag-reducing surfactants feature a long service life and produce no degradations when compared with various polymer additives,and have been widely used in centralized district heating(cooling)systems. As the surfactants reduce the fluid turbulent friction drag,they will also deteriorate the heat transfer performance of the surfactant solution. To expand their applications in the heat transfer domain and understand the cause of the deterioration in heat transfer performance,some experimental study and theoretical analyses have been conducted of the turbulent heat transfer structures for the surfactant solutions. However,the foregoing is still at an exploratory stage and no final conclusion has been drawn. To facilitate further study,an analysis with a summing-up was performed of the recent research on turbulent heat transfer structures and of the achievements made both at home and abroad. Moreover,the problems existing in the current research were also analyzed with personal viewpoints being presented for future studies.
