2215 三次元移動境界問題に対する非構造移動格子有限体積法(G05-3 解析モデルと解析手法,G05 流体工学)  [in Japanese] 2215 Unstructured Moving-Grid Finite-Volume Method for Three-Dimensional Moving-Boundary Problems  [in Japanese]

Moving-boundary problems are dealt with in a lot of scientific research and engineering field. In the case using body-fitted coordinate system for these problems, it is important to calculate that moving-gird would not affect to flow field. Although limited for two-dimensional system, we have already proposed the unstructured moving-grid finite-volume method. The feature of this method is volume integrating for space-time unified domain, and the method is able to satisfy the geometric conservation lows. In this paper the method is developed to three-dimensional system for three-dimensional moving-boundary problem.
