長方形管内気液二相流の研究（第3報） : 水力相当直径の流動と圧力損失への影響 STUDIES ON TWO-PHASE GAS-LIQUID FLOW IN RECTANGULAR CHANNELS (Report 3) : Effect of Hydraulic Equivalent Diameter on Flow Behaviour and Pressure Drop 松村, 博久 MATSUMURA, Hirohisa 井手, 英夫 IDE, Hideo open access In the previous report, We investigated experimentally about the effects of the aspect ratio and the geometric situation which the width or the depth of cross section had long side on the frictional pressure drop and the flow behaviour of two-phase air-water flow in horizontal, inclined (15 degrees and 45 degrees from horizontal) and vertical channels with a constant hydraulic equivalent diameter. In this report, the frictional pressure drop and the flow behaviour under the influence of hydraulic equivalent diameter are investigated experimentally on the rectangular channels with a constant aspect ratio.　Then the considerations are taken on the relation between the above results and the setting angle and the geometric situation of the test section. 鹿児島大学 Kagoshima University 1977-11 jpn departmental bulletin paper VoR http://hdl.handle.net/10232/12721 https://ir.kagoshima-u.ac.jp/records/2267 0451212X AN00040363 鹿児島大学工学部研究報告 The research reports of the Faculty of Engineering, Kagoshima University 19 35 42 https://ir.kagoshima-u.ac.jp/record/2267/files/AN00040363_v19_p35-42.pdf application/pdf 9.2 MB 2016-10-27 1977-11
