壁面剪应力 meaning in English
wall shear stress
Examples
- The method for improving the measuring accuracy of the wall shear stress by electrochemical technique
提高电化学法测试壁面剪应力精度的方法 - It is found that drag reduction occurs with adequate wavenumbers and grows with an increase of h . the mechanisms are revealed through variations of velocity profile and the decrease of wall shear stress
分析减阻机理是流速分布曲线及近壁区速度梯度介于层流与湍流之间， h值增大引起壁面剪应力显著下降。 - 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 ，在可渗透边界条件下弯曲血管内的浓度场分布，并分析了诸如壁面剪应力及跨壁流量等参数对传质的影响。计算表明随着dean数的增加，定常层流开始失稳。血管截面内侧区是浓度分布较高区域，并且随着dean数和peclet数的增加，内侧区浓度明显增大。
