摘要：
Gas-solid fluidized beds are widely used in energy, chemical, pharmaceutical, metallurgy and many other industrial fields. In this study, the flow behavior of non-spherical particles in typical fluidized beds is evaluated by coupling computational fluid dynamics and discrete element method simulations. The results show that the rotational granular temperature distribution of spherical particles in typical fluidized beds is nearly isotropic, and the rotational granular temperature distribution of non-spherical particles is obviously anisotropic. In addition, with the increase of particle aspect ratio, both translational granular temperature and rotational granular temperature increase, indicating the increase in the fluctuations of particle translational and rotational velocities. © 2023 Science Press.
