静電容量の変化を利用した液滴の粒径とその速度の測定(Ⅰ) Measurement of the Droplet Sizes and Velocities by a Capacitance Method 玉野, 和保 タマノ, カズホ 北山, 正文 キタヤマ, ヨシフミ Tamano, Kazuho Kitayama, Yoshifumi application/pdf In order to study heat transfer with a mist flow and the vapor condensation, it is strongly desirable to measure locally droplet sizes and the velocities. A new method has been developed for this purpose, in which capacity changes is produced by movement of droplet along the double needle probe. The applicable ranges of this method are: droplet size range; 1. 9～3.1 mm, and the velocity range; 0.5～1.4 m/sec. In the measurement of the droplet size profile for the spray in a vertical channel, the measured and pre-set maximum mist sizes; 300μm, agree within ±10%. departmental bulletin paper 広島工業大学 1976 VoR application/pdf 広島工業大学研究紀要 10 123 128 AN0021271X 03851672 https://it-hiroshima.repo.nii.ac.jp/record/293/files/kenkyukiyo10123.pdf https://it-hiroshima.repo.nii.ac.jp/records/293 jpn
