吹出し管を備えた吸込みノズルの空気輸送特性に及ぼすノズル深さの影響 Effect of Nozzle Depth on Pneumatic Conveying Characteristics of Suction Nozzle with Injection Pipe 福原, 稔 115057 Fukuhara, Minoru 高本, 健太 144097 Takamoto, Kenta 小田, 啓貴 144099 Oda, Yoshitaka 小嶋, 良昌 144102 Oshima, Takaaki 髙口, 裕芝 124013 コウグチ, ヒロシ Koguchi, Hiroshi 片野田, 洋 115052 Katanoda, Hiroshi Pneumatic conveying Suction nozzle Loading ratio Efficiency Fluidization In the vacuum system of pneumatic transport, the authors have proposed, that a suction nozzle equipped with an injection pipe at the center, would provide a highly-dense therefore a highly-efficient method of transporting a powder. In this paper, we examine the effect of nozzle length, the inserted depth of the suction nozzle into the powder bed. The resulting data show that the nozzle performance improved in a range of lower nozzle depths, but saturated in a range of higher nozzle depths with no insertion length of injection pipe. The powder behavior near the suction nozzle at different nozzle depths was observed with powder flow visualization. journal article 粉体工学会 2012-02-10 NA 粉体工学会誌 2 49 92 99 Journal of the Society of Powder Technology, Japan 18837239 AN00222757 https://doi.org/10.4164/sptj.49.92 http://hdl.handle.net/10232/0002000330 https://ir.kagoshima-u.ac.jp/records/2000330 jpn https://doi.org/10.4164/sptj.49.92 open access
