Highlights

• Effects of vertical jet on flow behavior were investigated using a filtered two-fluid model.

• Distributions of solid volume fraction and particle velocity were simulated.

• Vertical jet penetration lengths at different jet gas velocities were studied.

• The predicted air jet penetration length by several empirical correlations was discussed.

Abstract

The influence of a vertical jet located at the distributor in a cylindrical fluidized bed on the flow behavior of gas and particles was predicted using a filtered two-fluid model proposed by Sundaresan and coworkers. The distributions of volume fraction and the velocity of particles along the lateral direction were investigated for different jet velocities by analyzing the simulated results. The vertical jet penetration lengths at the different gas jet velocities have been obtained and compared with predictions derived from empirical correlations; the predicted air jet penetration length is discussed. Agreement between the numerical simulations and experimental results has been achieved.
