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 。 -
4 were calculated in curved tube with permeable arterial wall and effects of parameters, such as shear stress, mass flux of arterial wall, on mass transfer were studied. it was found that steady laminar flow become unsteady with the increase of de. the concentration in inner section of transverse section of the tube is higher than other areas, and with the increase of de and pe, the concentration there increase obviously. it indicates that for the permeable arterial wall, the macromolecules are likely to gather in the areas where axial velocity and shear stress are relatively low, thus indicates why location of atherosclerosis frequently occurs at inner side of curved tube
4 ，在可滲透邊界條件下彎曲血管內的濃度場分佈，並分析了諸如壁面剪應力及跨壁流量等參數對傳質的影響。計算表明隨著dean數的增加，定常層流開始失穩。血管截面內側區是濃度分佈較高區域，並且隨著dean數和peclet數的增加，內側區濃度明顯增大。
