並列タイトル等Computation of the Two-Dimensional Incompressible Navier-Stokes Equations Using an Implicit Factored Method
タイトル（掲載誌）航空宇宙技術研究所特別資料 = Special Publication of National Aerospace Laboratory SP-3
一般注記An implicit factored scheme was used for solving the two-dimensional incompressible Navier-Stokes equations. Pseudo compressibility was introduced in the continuity equation. The non-conservation from was chosen for stability. Von Neumann stability analysis with a model scalar equation showed that the present scheme remains stable under arbitrary coordinate transformations, without adding any numerical dissipation term. Calculation was made for a backward-facing step flow with the Reynolds number Re= Upeak H /nu= 58, where H is a step height. Convergence was obtained after about 300 iterations, using a non-dimensional time step DELTAt = 1.0. The calculated results show a reasonable tendency, except that small oscillations appear in the pressure distribution near the corner point. This phenomenon needs to be further investigated.
