概要

• 論文の詳細を見る

• The effect of ambient air temperature on the minimum fluidization velocity U_mf of glass beads is investigated by Distinct Element Method (DEM). Under different ambient air temperatures, the pressure drop curves are calculated by DEM to determine U_mf. The mean kinetic energy E of particles is defined to judge whether the particles move or not. The fluidization characteristics of fluidized bed are investigated in details. The calculated U_mf is compared with empirical data. The different behavior of Geldart B and D particles against temperature is reproduced numerically. U_mf decreases with increasing ambient temperature for Geldart B particles, while it increases for Geldart D particles.
