補間擬似粒子法による自由表面問題の数値解析 Numerical Analysis of Free Surface Problems Using Cubic Interpolated Propagation Method
Recently, several new simulation methods using the non-orthogonal element have been developed to preserve the original shape of a casting in its simulation model. However, the CFL number, which is one of the most important parameters for decreasing the consumption of the calculation time, is restricted to preserve the accuracy of the calculation in many of these methods. In this paper, a new mold filling simulation method based on the Galerkin method is proposed. It adopts the CIP (Cubic Interpolated Propagation) method in the governing equations to trace the surface of the liquid as accurately as possible. 3-D mold filling simulation in a circular disk with a gate and runner is demonstrated as the numerical example. The numerical result shows that the change of the main flow direction is caused by the pressure gradient force generated near the gate.
