直接差分法による湯流れの3次元コンピュータシミュレーション Three Dimensional Computer Simulation of Mold Filling of Casting by Direct Finite Difference Method
This paper presents an algorithm for simulating three dimensional fluid flow during mold filling of castings. The method for the discretization of mass and momentum conservation equations is based on the direct-finite-difference-method (DFDM). It is intended to simulate fluid flow with high accuracy and short CPU time. Efforts were especially made to model the shape of a free surface and calculate mass and momentum fluxes within the vicinity of the free surface regions. The reliability of the model was verified by comparing the simulated results with the experimental ones, and good agreements was achieved.
