吹吸射流协同驻波电帘增强颗粒物定向运输的研究
Research on improving directional particle transport on the surface of standing wave electric curtain using blowing and suction jet streams
摘要
Abstract
To address the challenge of achieving effective particle transport in standing wave curtains(SWC),the blow-suction jet(BSJ)technique was employed to improve the directional transport ability of particles,ensuring efficient particle removal from the SWC surface.A multiphysics simulation was used to investigate the directed transport behavior of particles within the BSJ-SWC system,examining the influence of the maximum applied voltage,voltage frequency,jet velocity and particle size on the particle trajectory.The spatiotemporal evolution characteristics of particles on the curtain surface at different jet speeds and particle sizes were analyzed.The experimental validation confirmed the effectiveness of the BSJ in improving particle removal from the SWC surface.The results show that the synergistic effect of BSJ significantly improves the directional transport capacity of particles on the SWC surface and thus ensures effective particle removal.Both BSJ speed and peak voltage can play a crucial role in particle removal efficiency.In particular,the enhancing effect of BSJ on particle removal is only evident when the jet velocity exceeds more than 0.3 m/s.When the jet velocity is less than 0.3 m/s,the particle removal performance of the SWC may be impaired.The particle removal efficiency of the BSJ-SWC system is positively correlated with the peak voltage.关键词
