 note = {3D CFD simulation was performed to examine the internal flow in a LNG turbopump. Rocket Engine Research Center of JAXA has been constructing an engine test bed, in which LNG (Liquid Natural Gas) is used as a propellant. The engine test bed has a LOX/LNG turbopump to pressurize propellants. The LNG turbopump section was built so far and the preliminary tests of this section have been started. The LNG turbopump uses an open impeller to meet the requirement of a low specific speed of 87 (m, cu m/min, rpm) and to avoid manufacturing complexity. A balance piston is adopted to keep thrust balance. The internal flow network is very complex and hard to estimate flow rates inside the pump in experiments. CFD analysis was performed for the LNG turbopump section to estimate internal flows and to predict performances of the pump. The calculated results were compared with experimental data and showed reasonable agreements., 資料番号: AA0048469036, レポート番号: JAXA-SP-04-012},
