水平チャネル内固気二相流の数値シミュレーション : 粒子ソース項のモデリングおよび反発モデルの改良

抄録

A nemerical simulation was made to predict distributions of concentration, particle and gas velocities. In this paper, a new model of the particle source term is presented for calculation of gas-phase flow. The present model is more efficient than the PSI-Cell (particle Source In Cell) model which was widely used by earlier investigators. A new model is also presented to calculate purticle bouncing on the wall. This bouncing model does not need any empirical parameters which depend on experimental results of pneumatic transportation.
