- 出版タイプ： NA高速炉燃料の再処理過程において,溶解・清澄槽内に,せん断及び溶解工程から発生する固体成分(スラッジ)が堆積する。また,ガラス固化過程でも,ガラス溶融炉内において,廃液中の白金族元素が炉底部に堆積する課題が確認されている。スラッジが溶解・清澄工程内の機器の作動や送液に与える影響や,白金族元素の堆積挙動を調査するために,粒子挙動を正確に予測可能な固液2相流解析コードの開発を行っている。 本件は,固液2相流の数値解析手法として,粒子間力及び粒子-壁間の作用について,離散要素法(DEM : Distinct Element Method)を用いた解析コードを作成し,様々な体系で検証を行った。その結果,作成した解析コードを用いた解析によって,粒子間衝突を正確に模擬可能であり,粉流体に特有な偏析現象を再現可能なこと,流れ場中の粒子挙動について,大局的に実験値とほぼ一致する結果が得られること,が明らかになった。At reprocessing operation of fast reactor fuels, sludge is generated by shearing and dissolution processes. The sludge accumulates on a bottom of dissolution and clarifying tank. It is useful for stable operation to investigate effects of the sludge on mechanical devices and fluid flow in the tank. In addition, at vitrification operation, there is a problem that noble metals in a high-level liquid waste accumulate on a bottom of a melter. A numerical simulation of solid-liquid two phases flow is desirable to solve these problems. In this study, a numerical simulation code for solid-liquid two phases flow was created based on a DEM (Distinct Element Method). DEM is an effective method to simulate collision of particles or particle and wall. This code was verified at some systems. As a result, segregation phenomenon, which is typical for powder and particles, is reproduced by the simulation code. Moreover, simulation results of particle behavior in flow fields agree with practical results in a large sense.
