摘要
实验测试了矩内颗粒的线速度 ,空隙率分布和颗粒卷吸量 ,结果表明颗粒瞬时速度高达 10m/s且与射流气速有一个数量级的滑移 。
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.
