摘要 对不同的浓度和温度下阳性离子表面活性剂十六烷基三甲基氯化铵(CTAC)在循环回路系统中的减阻特性进行了实验研究。表面活性剂呈现明显减阻特性,且各浓度条件下均存在一个临界温度,并表现出温度效应。本文从微观尺度和能量分析角度来解释这种温度效应。通过分析该表面活性剂溶液阻力减小和传热性能降低之间的关系,提出了通过对溶液温度的控制来改变减阻溶液的传热特性的方法。 Experiments were conducted to study the drag-reduction characteristics of the surfactant solution（CTAC/NaSal） under different concentrations and temperatures condition in a water loop system.It was found that the cationic surfactant solution showed greatly drag-reduction characteristics, and there existed a critical temperature at each concentration.It also demonstrated the temperature-effect phenomenon.In this paper,we explained this phenomenon based on micro-scale and energy analysis.According to analyzing the relationship between the drag reduction and the heat transfer reduction,we proposed a new approach to change the heat transfer characteristics of drag-reducing solution by controlling the temperature.
