中文摘要 | 本文利用Eringen之微極性流體理論分析經過具可穿透壁之二維或軸對稱物體之微極性流體之穩態層流混合熱對流。文中探討的是材料參數、浮力參數、質量傳遞參數、普朗特數及不同之熱邊界條件對於摩擦係數及紐塞數之影響。分析中先應用一適當之轉換,然後再以一隱式有限差分法解之。數值結果與已發表之數據相比較非常吻合。 |
英文摘要 | The steady-state laminar mixed convection of micropolar fluids past two-dimesnional or axisymmetric bodies with permeable walls has been analyzed using the theory of micropolar fluids due to Eringen. Of interest are the effects of material parameters, buoyancy parameter, wall mass transfer parameter, the Prandtl number and the distinct thermal boundary conditions on the local skin coefficient and the local Nusselt number. The problem was formulated by applying a suitable transformations and the solution was obtained by using an implicit finite difference method. The numerical results compared with published data sets are very agreeable. |
