Abstract: 本研究藉由求解穴流(cavity flow),評估分割操作有限解析法(fractional-step finite analytic method)、混合有限差分法(hybrid finite difference scheme)與CS內插特性法(characteristics method with cubic-spline interpolation)之計算結果。在數值穩定性方面,分割操作有限解析法僅於低雷諾數時可以求解出穴流穩定狀態(steady state),而混合有限差分法與CS內插特性法,無論雷諾數高低皆能求解,為穩定之數值方法。在準確性考量上,混合有限差分法與CS內插特性法準確度相似,但CS內插特性法略優於混合有限差分法,而分割操作有限解析則有誤差產生。
