Moreover, this paper investigates the influences of surfactant aqueous solutions on flow characteristics of a mmc. sodium dodecyl sulphate aqueous solution and alkyl polyglycoside aqueous solution are used as working fluids. the experiment results indicate that the drag reduction depends on flow velocity and temperature ; the drag reduction effects aren ’ t very obvious in laminar flow region, but when fluid enter turbulent flow region, the drag reduction increase notably, the drag reduction effects
研究結果表明，阻力減小率（ dragreduction ， dr ）與流速和溫度有關;層流區內表面活性劑的減阻效果不是特別明顯，但進入紊流區后減阻效果開始增強，尤其進入旺盛的紊流區后減阻效果大大增強;溫度提升也可增加dr ，但在溫度較高時添加sds后減阻效果的改善卻不及apg 。
