Heretofore, an experimental investigation was conducted to determine the cooling characteristics of LH2 and combustion efficiency characteristics by using a sub-sized combustor with channel wall construction. In this report thermo-hydraulic behavior of the coolant in the channels of the combustor was investigated by using an improved combustor. The following conclusions are based on studies of two combustors. 1)Liquid hydrogen heat transfer correlations including the asymmetric heating effects were derived. These empirical equtions were able to predict over 95% of all the present experimental data within ±20% errors. 2)The correlation for the characteristic velocity efficiency was empirically derived. The equation succeeded in correlating all data within ±2% errors. To verify the usefulness of these results, the relationships between the present subsized combustors and the full-sized“LE-5”engine, were discussed., 資料番号: NALTR0767000, レポート番号: NAL TR-767}, title = {小型溝構造液水冷却燃焼器の研究(第3報)(大型燃焼器との関連性)}, year = {1983} }
