Book excerpt: The objective of this investigation is to numerically predict the effect of an electric field on a two-dimensional gas-solid fluidized bed. The particles in the bed are taken to be of a uniform size and density forming the particulate phase with a gas (air) taken as the continuum phase. A hydrodynamic model of fluidization utilizes the principles of conservation of mass and momentum describing the multiphase flow equations along with the constitutive equations of gas-solid drag and solids stress. A two-dimensional unsteady-state computer code (K-Fix) was used to observe the effect of an electric field on the gas and solid velocities and the void fraction and pressure in the bed. Special case studies included that of a jet, a bubble, and two bubbles, with and without an electric field.
