On impacts of solid properties and operating conditions on the performance of gas-solid fluidization systems

The characteristics of gas-solids two-phase flow and fluidization in terms of the flow structures and the apparent behavior of particles and fluid-particle interactions are closely linked to physical properties of the particles, operating conditions and bed configurations. To assist the development of useful strategies for the design of fluidized-bed reactors, this paper discusses both positive and negative impacts of particle sizes, bubbles, clusters, and column walls on the fluidized-bed reactor performance.
