1. IntroductionFluidized beds are extensively utilized in the energy and chemical industries. Gas–solid two-phase flows within fluidized beds—such as those involved in coal powder combustion, biomass gasification, pyrolysis, and desulfurization—entail the mixing of multi-component particles [1,2]. In coal combustion processes, the interaction between catalyst particles and coal particles is critical for optimizing fluidization behavior and enhancing the combustion efficiency of coal.
