直接差分法による湯流れシミュレーション法

抄録

  An algorithm based on the direct finite difference method with staggered mesh is proposed to simulate mold filling with melt front. The flow model in the method has been made clear, showing necessity to use up-wind velocity for convection term. Shape of melt front is estimated from filled volume in each element, and surface tension is considerd in the equation of motion. Good agreement is demonstrated between simulated and measured mold filling for a water model of gravity casting and aluminum die casting.
