Continuum Hypothesis in the Computation of Gas-Solid Flows

  • Chapter

Abstract

Dilute gas-solid particle flows are encountered in many industrial applications such as coal combustion equipment, cyclone separators and electrostatic precipitators, pneumatic conveying and pulverized coal gasification. There are basically two approaches commonly to predict gas-solid flows: Lagrangian and Eulerian. The fundamental concepts of both approaches and their specific applications have been discussed and reviewed in the literature [1]. In the Lagrangian approach, the motion of single particles are considered and relevant variables are calculated along the particle trajectories. The Eulerian approach treats both gas and particulate flows as continua, and the phases are regarded as two mutually interacting fluids.
