G0510406 高レイノルズ数におけるISO9300型臨界ノズルの特性評価試験([G051-04]流体工学部門一般セッション(4),流体工学部門)
詳細
We measured the discharge coefficient of critical nozzles using hydrogen gas in high Reynolds number (Re = 2.5 x 10^5 - 1.6 x 10^6). It was confirmed to deviate from the universal curve prescribed in IS09300, and to indicate high value of the critical back pressure ratio. In high Reynolds number, it was not necessary to take large differential pressure in the use of critical nozzle.
