VELOCITY OF FULL FLUIDIZATION OF A BED OF POLYDISPERSE GRANULAR MATERIALS
Yu. S. Teplitskii and V. I. Kovenskii UDC 532.546 Based on the principle of hydrodynamic equivalence, a technique to calculate the velocity of complete fluidization of polydisperse granular materials of different densities with allowance for the transformation of their initial size distribution has been worked out. Keywords: polydisperse fluidization bed, minimum of fluidization velocity, complete fluidization velocity, discrete size distribution of particles, continuous size distribution of particles, equivalent diameter of particles.
