Fluid and particle entrainment into vertical jets in fluidized beds

The flow of particles and fluid in the vicinity of vertical jets in fluidized beds was studied by using a two‐dimensional bed of lead shot fluidized by water. It was found that both interstitial fluid and solid particles are entrained into the jet as it expands and penetrates into the bed. An approx...

Description
Summary:The flow of particles and fluid in the vicinity of vertical jets in fluidized beds was studied by using a two‐dimensional bed of lead shot fluidized by water. It was found that both interstitial fluid and solid particles are entrained into the jet as it expands and penetrates into the bed. An approximate mathematical model is developed to describe the particle and fluid flow fields observed experimentally; from this, an expression is derived for rates of entrainment into vertical jets in fluidized beds, and a model is postulated for the flow fields around grid jets.
