中文摘要 | 本篇論文探討不同邊界對在二平行板間受剪力作用之球狀粒子流體的影響。使用 Jenkins and Richman [1] 在 1985 年所推導的 constitutive theroy 以及 Richman[2] 在 1988 年所推導的邊界條件( boundary conditions )於質量、動量、 能量平衡方程式 , 來探討快速流動於二平行板間穩態( steady state )、非均質( inhomogeneous )球 狀粒子流體之流動行為。 我們不僅證明不同邊界影響流體的速度、 顆粒集中( solid fraction )、顆粒溫度( granular temperature )、 應力( stresses )、與滑動速度 ( slip velocity ), 而且針對應力及滑動速度與 Richman[2] 在 1988 年所得的近似解 相互比較。 |
英文摘要 | The rapid flows of identical, smooth, nearly elastic spheres were considered here, which interact with a flat wall to which identical, evenly spaced half-spheres have been attached. The boundaryvalue problem for the steady inhomogeneous shear flows which are maintained by the relative motion of parallel bumpy boundaries was sloved by employing the constitutive relations of Jenkins and Richman [1] and boundary conditions of Richman [2] in the balance equations for mean fields of mass density of flow, velocity, and the granular temperature. How the resulting profiles of velocity, solid fraction, and granular temperature were affected by changes in the geometrical configuration of the boundary was demonstrated. Additionally, predicting how the induced stresses and slip velocity would vary with the geometrical configuration of the boundary and the average solid fraction within the flow was undertaken. Observed predictions for the slip velocities and induced stresses were finally put into comparison with those approximate solutions obtained by Richman [2], which are based upon the assumption that homogeneous flows occur for all. |
