摘要：

The hydrodynamics of a 'fast bubble' in a two-dimensional rectangular fluidized bed is studied numerically. The fast bubble (which moves faster than the fluidizing velocity) is produced by injecting gas through a jet for a short time into a bed at minimum fluidization. The numerical computations are in good agreement with the classical theories of Davidson, Jackson, and Murray and with experimental data, thus enhancing confidence in the computer modeling of the hydrodynamics of fluidization.
