Simulation of hydrodynamics in gas distribution devices for non-homogeneous mode of fluidization

An increase in the intensity of diffusion-controlled processes during granulation is provided by apparatuses with non-homogeneous fluidization, hydrodynamics which significantly depends on structural features granulator chamber and gas distributing device (GDD). The main problem formation stagnant zones working surface GDD, which, when supplying a coolant temperature that exceeds melting point granules, leads to solids termination process.
 In this work, simulation was carried out using SolidWorks 2022 SP2 for 4 types distribution devices (GDD) different configurations values ​​of cross-section coefficient GDD.
 analysis results shows most significant influence hydrodynamic activity index near GDD iha has φ, since even an insignificant value φ from 3.0 3.5% decrease at least 1.4 times all considered GDD. without taking into account presence solid granular material plate.
