Analysis of the Velocity and Concentration of Solid-Liquid Two-Phase Flows (The case of Heterogeneous and Homogeneous Flows between two parallel Plates)

摘要

The authors made an analytical model of the heterogeneous and homogeneous solid-liquid two-phase flows between two parallel plates, and investigated the velocity and concentration profiles estimated by numerical analysis of this model. We tried to avoid the use of too many experimental constants or coefficients of an arbitrary nature, and made the analytical model with well-known equations as much as possible. However, mutual interaction of particles and interaction between particles and walls are not considered in this model. After the comparison between estimated and experimental values, we obtained the following conclusions: the estimated velocity and concentration profiles almost agree with experimental ones, and these profiles agree well within a tenfold distance of between two flat plates under the same Fr number.
