Fluidization of solid particles
WebWhen the solid particles are fluidized, the fluidized bed behaves differently as velocity, gas and solid properties are varied. It has become evident that there are number of regimes of fluidization, as shown in Figure 2.1. When the flow of a gas passed through a bed of particles is increased continually, a few vibrate, but still WebApr 10, 2024 · There are two obvious flaws in DEM simulations of gas–solid fluidized beds: (1) Although A-Type particles are generally thought to be most fluidizable, most DEM …
