| 摘要: |
| 为了分析湍流减阻技术的可行性,探索减阻效果与溶液温度、浓度和流动雷诺数的关系及减阻水溶液的抗剪切特性,对阳离子表面活性剂十六烷基三甲基氯化铵(CTAC)水溶液进行减阻实验．结果表明,CTAC水溶液具有较强的抗剪切能力,但在高温条件下(70 ℃)减阻现象消失．CTAC水溶液减阻技术应用在集中供热／供冷系统中,尤其在地板辐射采暖系统中是可行的． |

| Abstract: |
| To analyze the feasibility of turbulent drag-reducing technique, and explore the relationship between drag reduction and solution temperature, concentration and flow Reynolds number and the characteristics of resisting the shear, cetyltrimethyl ammonium chloride (CTAC) aqueous solution have been investigated experimentally in this paper. The experimental results show that CTAC aqueous solution has strong ability of resisting the shear, and the drag-reducing effect of CTAC aqueous solution disappears when the solution temperature reaches 70 ℃. The experimental results will provide the important reference value and instruction meaning for the application of CTAC aqueous solution in a district heating／cooling (DHC) system, especially in the radiant floor heating (RFH) system. |
