Abstract
The influence of horizontal jet on flow behavior of gas and FCC particles is predicted using a filtered two-fluid model proposed by Sundaresan's group in a cylindrical fluidized bed. The distributions of velocity and solid volume fraction along lateral direction are investigated by analyzing the transient simulation results at the different height of the fluidized bed. The jet penetration lengths of different jet velocities have been obtained and compared with published experimental data as well as with predictions of empirical correlations. The predicted air jet penetration length by several empirical correlations is discussed in the gas–solid bubbling fluidized bed. An agreement between the numerical simulation and experimental results has been achieved.
