並列タイトル等Heat Transfer Characteristics of Liquid Hydrogen at Super Critical Pressure (Heat Transfer Experimental Data and Comparisons with Previous Correlations)
タイトル（掲載誌）航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-583
一般注記The cooling problem in the thrust chamber is one of the most critical problems in the development of the rocket engine. Thus the engine system design is often greatly influenced by the decision of what kind of cooling system to adopt. The nondimentional design equations, which were previously proposed by many investigators, however, are very different from each other. Consequently we can not decide what is the best adequate equation for the design. Such being the case, the authors have begun investigation of the heat transfer characteristics of liquid hydrogen in relation to the design of engines being developed in Japan. The authors consider the main causes of the disagreement between many correlation equations to be as follws. (1)Many investigators did not distinguish among the differences of heat transfer phenomena found near the pseudo critical temperature T*cr. (2)The investigators did not pay enough attentions to the surface roughness of the test tubes and the complicated behavior of the entrance effects. Thus the present report intends to compare the author’s experimental data with these previously correlated equations from these two points of view.
