往復運動する伝熱面からの対流熱伝達 Convective Heat Transfer from Heat Transfer Surfaces in Reciprocating Motion 橋詰, 健一 ハシヅメ, ケンイチ 中石, 大輔 ナカイシ, ダイスケ Hashizume, Kenichi Nakaishi, Daisuke 533.1 Convective Heat Transfer Heat Transfer Coefficient Reciprocating Motion Equivalent Reynolds Number application/pdf An experiment was conducted to investigate the heat transfer characteristics of surfaces in reciprocating motion. The test surfaces were flat plates having vertically brazed cylinders. Comparing the experimental data in reciprocating motion with those of forced convection, it was revealed that a bias Reynolds number exists, which may be due to the un-steady convection effect. The bias Reynolds number depends, within this experimental range, not on the moving speed but on the surface geometry. The heat transfer coefficients in reciprocating motion agreed well with those of forced convection using the equivalent Reynolds number, which consists of the ordinary Reynolds number and the bias Reynolds number. 広島工業大学 2006 jpn departmental bulletin paper VoR https://it-hiroshima.repo.nii.ac.jp/records/721 AA11599110 13469975 広島工業大学紀要. 研究編 40 33 37 https://it-hiroshima.repo.nii.ac.jp/record/721/files/kenkyuhen40033.pdf application/pdf 254.3 kB 2023-03-30
