Effect of echeloned supply of a swirling air flow on particle layer formation in a vortex chamber

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 o...

Description
Summary: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.
