摘要: Abstract Flow behavior of gas and particles is performed by means gas–solid two-fluid model with the second-order moment in bubbling fluidized bed. The distributions velocity moments are predicted beds. Predictions compared experimental data measured Jung et al. (2005) a bed Patil experiments jet. simulated vertical direction on average 1.5–2.3 times larger than that lateral (Jung al., 2005). For jet, ratio normal to range 0.5–2.5 (Patil bubblelike Reynolds stresses per unit bulk density used Gidaspow (2002) computed from hydrodynamic velocities. 4.5–6.0 predictions agreement porosity (2005).
