arterial shear stress 中文意思是什麼
arterial shear stress
解釋
動脈剪應力-
The transport of macromolecules in curved tubes with permeable arterial wall was simulated numerically. the fields of axial velocity, the fields of secondary flow function and the distribution of wall shear stress along the transverse section of arterial wall were obtained under different dean number, 10
10800 ，計算了彎曲血管內的二次流軸向速度場和剪應力沿管壁分佈的情況。計算求得了在不同dean數和peclet數下，其中10 -
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。
