Dynamic Aggregation of Fine Particles in Gas-Fluidized Beds

  • José Manuel Valverde Millán
Part of the Particle Technology Series book series (POTS, volume 18)

Abstract

Individual fine particles suspended in a gas flow undergo a process of aggregation due to interparticle attraction. As the aggregate grows in size, the gas drag force on the surface of the aggregate increases to compensate the aggregate weight. Thus, the size of the aggregate becomes limited by the balance between the shear force exerted by the gas on the particles in the aggregate outer ring and interparticle attractive force. In this chapter, a fundamental equation is developed to predict the size of these dynamic aggregates.
