The conclusions about the nature of bed fluidization and the rate of polyfractional material entrainment in the cylindrical vortex chamber with the air supply through the lower and upper end swirlers were drawn, based on the visual observation of the fluidized bed, the determination of entrainment of the bed dispersed material by weighing the material after a given time of vortex chamber operation, and also by means of the numerical simulation of dynamics of the fluidized bed of particles.

旋流气流的阶梯式供应对涡流室内颗粒层形成的影响

在流化床的目视观察的基础上，得出了关于床层流化性质和通过上下端旋流器供气的圆筒形涡旋室中多组分物质夹带率的结论，并基于流化床的目测确定了夹带通过在给定的涡流室操作时间后称量物料，并还通过颗粒流化床动力学的数值模拟，使物料床层分散。
