  1. Theory calculation and derivation demonstrate that the heat conduction of membrane exerts little influence on performance. the characteristics of mass transfer through membrane are mixed flow including knudsen flow and poiseuille flow, which moreover, vary with operational variables

    理論推導與計算表明：膜的導熱性對真空膜蒸餾過程的影響可以忽略，膜蒸餾過程膜內質量傳輸機制是努森流與粘性流共同作用的混合流機制。
  2. According to the experiment of influences of fiber structures and the width of edge channel on flow filling, it was found that even a small gap ( l or 2mm ) between the preform and the mold edge could also disrupt the flow pattern, which evidently changed the local permeability of preform. the filling process was simulated using the permeability for different edge width predicted by a. hammami or poiseuille model, which shown good agreement with the experiment results

    實驗研究了纖維鋪層結構及流道縫隙的寬度對充模流動的影響，發現在纖維預成型體和模具壁間存在的較小的縫隙也會對邊緣的流動產生干擾，進而影響增強材料主體的滲透；對于不同的縫隙寬度，分別根據a . hammami模型和poiseuille模型預測邊緣等效滲透率，並進行充模過程數值模擬，與實驗結果吻合較好。
  3. ( 2 ) with f varying, there exists a number fr which is about - 1 ( curvature, torsion and dean number have little influence on fr ), when f > fr, the maximum of the axial velocity is near the outside bent and the friction factor ratio increases with f increasing ; when f < fr, the maximum is near the inner side bent and the ratio increases with f decreasing ; when f = fr, the distributions of the axial velocity are similar to those of poiseuille flow and the friction ratio is about 1

    （ 2 ）當f變化時，存在確定的數值fr （ fr在- 1左右。曲率、撓率和dean數對fr的影響很小） ，當f fr時，軸向速度最大值偏向外側，摩擦系數比隨f增大而增大；當f fr時，軸向速度最大值偏向內側，摩擦系數比隨f減小而增大；當f = fr時，軸向速度的分佈和poiseuille流近似相同，摩擦系數比約為1 。
  4. Plane poiseuille flow

    平面泊肅葉憐
  5. In present dissertation, firstly an analytical study on the force and deformation of an er single chain under poiseuille flow is presented from the point of microscopic view. an approximate solution of the poiseuille flow in a tube with rectangular cross is derived from galerkin approach. the balance equation of moment for the er chain is established to avoid using point - dipole model, which is not accurate enough in the case that dielectric particles are adjacent to each other

    本文首先從微觀的角度，分析電流變鏈在poiseuille流動中的受力以及變形，分析過程中推導了矩形截面管內poiseuille流動速度分佈的galerkin近似解，並採用理論力學軟索模型對電流變變鏈的受力進行分析，從而避免了點偶極子近似在粒子相距較近情況下引起的誤差。
  6. Poiseuille - hartman flow
