Staggered Discontinuous Galerkin Method for Fluid-structure Interaction
流固耦合(fluid-structre interaction)是模擬可動結構與周圍的流體相互作⽤的數學模型,是許多⼯程設計問題的關鍵。由Peskin[35]於1972年研發的浸⼊邊界法 (immersed boundary method)是其中⼀種流⾏的流固耦合求解⽅法。浸⼊邊界法起初⽤於⼼臟瓣膜⾎流的數值逼近,後來成功地引伸到其他應⽤。在浸⼊邊界法中,固體施予流體的⼒項包含狄拉克 函數,此項在伽遼⾦(Galerkin)⽅法中可以⾃然地處理。此外,浸⼊邊界法的其中⼀個誤差來源是容積流失,透過加強推動拉格朗⽇標記點的流體速度的無散條件,此誤差可被改善[39]。 === 最近,[9]提出⼀種新的...
