The results show that the pressure loss tendencies against the bearing revolution speed were significantly different between the flow directions. It was mainly caused by the flow separation behind the ball and centrifugal force effect of swirl flow made by bearing revolution. Furthermore, we get a simplified pressure loss model of the bearing and it can approximately estimate the difference of the pressure losses between the flow directions., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065211000, レポート番号: JAXA-RM-11-013}, title = {ロケット用ターボポンプ玉軸受の冷却流れ圧力損失モデル}, year = {2012} }
