Exploration of the interaction dynamics between plasma and fluidized particles in a fluidized-bed holds practical importance for elucidating mechanism treatment powders. In this study, we employed 2D fluid model to investigate effects particle diameter, dielectric constant, inter-particle spacing, with primary aim simulating specific consequences variations size, material type, gas-to-powder ratio (GPR) on powder processing effect. The results indicate that diameters below 300 μm exert less impact streamer propagation, enabling complete wrapping surface (100%). However, diameter 400 induce branching, leading reduction area 46%. These observations imply critical size range 300–400 achieving effective particles. Plasma ensures comprehensive coverage low constants (εr<4), while possessing higher constant (εr>8) exhibit diminished plasma-treated (80%), meaning longer durations high materials may be required achieve comparable Furthermore, as spacing increases from 10 500 μm, undergoes an initial increment, followed by subsequent reduction. Notably, at channel displays root-like branching pattern, substantial expansion area. This indicates optimal GPR system can enhance
