| Abstract: | Based on basic mechanics theory of particle media,two possibilities including particle leaking from louver plate and particle stopping on louver plate were analyzed;and the design criteria for louver plate were established,which agree well with the experimental results.Three factors of louver plate such as its length( d 3),distance ( d 4) and angle from the horizon (θ) could be determined as followed:θ≥π2-φ i 2+φ w 2- cos -1 sin φ w sin φ i 2, d 4d 3<( tg φ i + tg θ) cos θ[HT7”SS] [WT5HZ]tangular cross- |
