Abstract

固体から流体までの媒質に対する揺動現象を解析するために,固体と流体双方に適用できるLagrange座標系の支配方程式を整理し,有限要素法による数値解析を実施した.媒質の入った矩形容器を傾ける数値解析を行い,流体への適用性を確認した.また,揺動現象の解析を実施して固体と流体での自由表面形状が異なることを指摘した.

 We focus on sloshing behavior of intermediate state of solid and fluid, which simply model a liquefied layer. In order to simulate the behavior, we introduce common governing equaions representing both solid and fluid materials, and develop a numerical scheme in Lagrange coordinate system. It is verified by two types of numerical simulaitons: static behavior on a tilted recutangular tank and sloshing behavior. From the simulation results, free surface shapes are different between solid and fluid.
