STABILITY OF FLOWS IN FLUIDIZED BEDS Academic Article uri icon

abstract

  • We study the linearlized stability of the state of uniform fiuidization, within the context of the theory of mixtures. The mixture is assumed to be made up of a classical linearly viscous fluid infused with particles. In marked departure from most of the previous studies, we model the solid as a granular material and assume a constitutive relation that stems from classical motions in continuum mechanics. The linearized stability analysis of the state of uniform fiuidization, in general, for a three-dimensional disturbance leads to an eighth order equation for the characteristic whose root implies instability, when positive. © 1996, Taylor & Francis Group, LLC.
