スリットプローブによる粉じん濃度測定誤差 <論文> Dust Sampling Error Using a Slit Probe 吉田, 英人 Yoshida, Hideto 大杉, 健 Ohsugi, Takeshi 増田, 弘昭 Masuda, Hiroaki 井伊谷, 鋼一 Iinoya, Koichi 570 To examine the error in measuring particle concentration due to anisokinetic sampling over a wide range of inertia parameters, theoretical and experimental studies have been conducted by using methyleneblue-uranine aerosol generated by a spinning disk and lycopodium spores in the small and large inertia regions, respectively. The theoretical results obtained assuming potential flow agree well with the experimental values in the small inertia region. On the other hand, the experimental result is smaller than the theoretical one in the large inertia region. It is also recognized that the concentration error becomes smaller as the sampling velocity becomes extremely high. The amount of particles deposited in a probe is also examined to show that this amount cannot be ignored in practical applications. http://purl.org/coar/resource_type/c_6501 日本材料学会 1976-07-15 VoR 0514-5163 AN00096175 667 材料 274 25 670 667 材料 https://hiroshima.repo.nii.ac.jp/records/2010016 jpn 110002299860 http://www.journalarchive.jst.go.jp/japanese/jnlabstract_ja.php?cdjournal=jsms1963&cdvol=25&noissue=274&startpage=667 open access 社団法人日本材料学会 本文データは学協会の許諾に基づきCiNiiから複製したものである
