Abstract：This paper investigates the collection charateristics of a solid particle collection system utilizing ventilation under microgravity conditions,establishes a mathematical model of the solid particle collection system,performs numerical simulations of collection performance under various operational parameters,and identifies an inlet ventilation structure with superior collection efficiency.An experimental platform was developed using parabolic flight tests,through which collection and distribution outcomes of solid particles under different operating conditions were obtained.The results were compared and validated against numerical simulations,leading to the identification of optimal operating parameters for solid particle collection in microgravity.
