| Abstract: | The mixing characteristics of jet streams in a G-S fluidized bed was investigated. The velocity, the voidage distributions and the entrainment of particles in jet streams were measured.The results show that the instantaneous velocity of particles reaches 10 m/s and the velocity slip between gas and particles in the streams is in one order of magnitude.It gives an evidence for the mechanism of fast heat and mass transfer and chemical reactions in the jet agitated fluidized bed. |
