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。
The drag reduction characteristics of cetyltrimethylammonium chloride (CTAC), a cationic surfactant, in a circulation system at different concentrations and temperatures were investigated experimentally. The surfactant shows obvious drag reduction characteristics, and each concentration has a critical temperature, and shows the temperature effect. This paper explains this temperature effect from the microscopic and energy perspectives. By analyzing the relationship between the decrease of the resistance of the surfactant solution and the decrease of the heat transfer performance, a method of changing the heat transfer characteristics of the drag reducing solution by controlling the temperature of the solution is proposed.
