• Drag Force Model for Fluidized Bed with Poly-Dispersed Particles

抄録

Generally, particles used in industrial fluidized beds have size distribution. When the size distributed particles are fluidized, they tend to segregate with each other. The segregation is caused by difference of drag force between larger and smaller particles. In the present paper, we focus on the drag force for a binary mixture of particles differing in diameter, and propose some drag force models for fluidized beds with the size distributed particle. An experiment under the same condition as the numerical simulation is performed to validate the proposed drag force models. We examine pressure drop property of the particle bed and how the segregation progresses as fluidizing time goes on both numerically and experimentally. The calculation results for each drag force model are compared with the experimental result.
