中文摘要
空穴流 (cavity flow) 典型探討問題為具黏性之穩態流場，受頂部平板運動所發展
而形成之渦漩結構，亦稱為頂部驅動流 (lid-driven flow)。本文引用 Ghia等 [1] 所求得
之二維方形 (square) 流場之標準解做為精確度分析指標，並探討二維問題之幾何形狀
對於空穴流影響，如矩形、非正交幾何與三角形幾何之空穴流，透過數值模擬並與相關
文獻進行驗證，其結果皆顯示良好的一致性。
英文摘要
One of the typical problems of cavity flow is the steady viscous flow field, developed by lid-driven motion (also named the lid-driven flow). The present study used the Ghia and Shin’s standard solution [1] to benchmark the accuracy of square cavity flow analysis. This paper aimed at the study of the effects of geometric configuration on the two-dimensional rectangular cavity flow. Applying numerical simulation method to square, non-orthogonal geometry and triangular cavity flow configurations, the results obtained were compared fa-vorably with those obtained from the literature.
