Abstract:Aiming at the difficulty in analyzing the flow characteristics of sepiolite powder in horizontal tubes, a simulation analysis method for the aerodynamic transport performance of sepiolite powder based on particle size and stress was proposed.Aiming at the smooth gas transmission of particles, the shear stress model of the sepiolite particles in the horizontal circular tube was constructed.The stress conditions of different particle size sepiolite powder in dilute phase gassolid phases the various force changes of the particles under specific process parameters, and the effects were analyzed.Finally, based on the COMSOL multiphase flow analysis software, combined with the force analysis conclusion, the twodimensional coupled particle tracking method was used for different sizes of sepiolite powder.Particle pneumatic conveying characteristics were analyzed and verified.The results show that under the specific process parameters, the stress state of the sepiolite powder in the horizontal round tube is closely related to the particle size.
