STUDY ON PNEUMATIC CONVEYING CHARACTERISTICS OF SPHEROCYLINDRICAL PARTICLES IN A 90° BEND PIPE

This study conducts a numerical simulation of the pneumatic conveying process of spherocylindrical particles in a 90°bend by coupling computational fluid dynamics (CFD) with the discrete element method (DEM). The focus is on analyzing the effects of inlet gas velocity, particle mass flow rate, particle aspect ratio, and pipe diameter on parameters such as pressure drop, the magnitude of average particle velocity at the outlet, the average particle collision number, and the average particle collision intensity. The results show that different parameter combinations have a significant impact on the conveying performance of the system. The quantitative findings enhance the understanding of the pneumatic conveying characteristics of spherocylindrical particles in a 90°bend and provide valuable insights for improving pneumatic conveying efficiency.
