Hirosaki Bunka Center), Hirosaki, Aomori, Japan, A new interface model in solid-fluid interaction problem is presented. A level set function is used for the definition of shapes and flow properties are corrected within three layers of stencils around interface. This approach is very simple and robust and can capture the detail of flow structures including discontinuities such as shock waves and slip lines etc.. Some basic important 2-D Euler flow problem are solved to verify effects of this approach with WCNS (Weighted Compact Nonlinear Scheme) including a new type of compact scheme to improve robustness including the transonic flow around a 2-D airfoil, the supersonic duct flow around a prism and a circular cylinder and the moving-shock/obstacle interaction problem (Schardin's problem). The extension of this method to the moving problem with body deformation is straightforward., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530023027, レポート番号: JAXA-SP-14-010}, pages = {151--155}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {固気相連成問題におけるインターフェースモデルの構築と高速流解析への応用}, volume = {JAXA-SP-14-010}, year = {2015} }
