Note (General): To investigate the effect of PSD on acoustic cavitation surge in turbopump, we conducted analyses with the resistance of PSD as a parameter. Consequently, we found that patterns of the acoustic cavitation surge were classified into three types by the value of the resistance. (1) First (the resistance of the PSD is smaller.), when the frequency of the inertial cavitation surge between the PSD and the turbopump coincides with the acoustic natural frequencies between the tank and the PSD, the acoustic cavitation surge onsets between the tank and the PSD. (2) Second (the resistance of the PSD is middle.), the inertial cavitation surge which occurs between the PSD and the turbopump is suppressed by the resistance of the PSD. However, when the frequency of the inertial cavitation surge between the PSD and the turbopump coincides with the acoustic natural frequencies between the tank and the turbopump, the acoustic cavitation surge onsets between the tank and the turbopump. (3) Third (the resistance of the PSD is larger.), when the effect of the PSD is lost, the acoustic cavitation surge just occurs between the tank and the turbopump with several harmonic frequencies.
