To test the effectiveness of this scheme, three problems are defined, namely, the backward-facing step, the blunt based body, and the rectangular cylinder obstacle. A detailed description is given on finite difference approximations of initial conditions, boundary conditions, and sharp corners for each problem. Also, a detailed description is given on finite difference approximations for the four investigated open boundary conditions. The results of numerical experiments showed that this scheme is stable and accurate as was expected, and also that there are large differences among the four open boundary conditions in flows in the domain near the open boundary, when the problem becomes more complicated.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
