| 英文摘要: |
| The work aims to analyze the application background of flexible biomass particles and propose two key factors (cleanliness and orientation distribution of biomass) affecting product packaging quality. The research achievements of biomass fluidization were summarized from the perspectives of numerical simulation methods, flexible particle modeling theory, and the applicability of the drag model. The solutions proposed by the research group in biomass characterization, biomass separation and orientation control were described. Machine vision technology was suitable for the measurement of physical and mechanical properties of biomass. Multi-inclined curved channels can be used for effective separation of mixed particles. The flow velocity gradient of the wedge-shaped channel can accelerate the orientation adjustment of non-spherical particles. The main problems in numerical simulation of biomass fluidization are summarized and future research plans are proposed. |
