- 出版タイプ： NA集中熱容量式(スラグ)カロリメータにより、750kWアーク加熱風洞気流の熱流束を計測した。銅製のスラグ表面には、種々の触媒特性のコーティングを実施し、その熱流束値への効果を調べた。熱流束値は、Cu、Niなどの金属表面で大きく、SiOなどのガラス質非触媒性表面では極めて小さいことが確認され、その序列は文献値と一致した。熱流束計測値は、ガードン式カロリメータの結果とオーダーで一致し、その平均的値のガードン計測値からの偏差は倍数1.8程度に収まった。この差違は、計測面積の相違、表面状態の不明確さ、流れ場の不均一などに由来すると推定される。This paper shows the application of a slug type calorimeter to the heat flux measurements of an arc-heated flow, and evaluates the effect of slug surface coatings with differing catalytic efficiency on measured heat flux. Metallic coatings are more catalytic and result in higher heat flux values than coating containing silica. These results are in accordance with the known order of catalytic effectiveness. Measured heat flux values agree in magnitude and lie within a factor of 1.8 of the values obtained by Gardon type calorimeters. Presumed sources of the difference are the difference in sensing areas, ambiguity of surface characteristics, and flow field nonuniformity.資料番号: AA0001979000レポート番号: NAL TR-1388
