초록

Hydraulic performance and cavitation characteristics of fuel pump in turbopump were studied experimentally. This fuel pump has a centrifugal impeller with a separate inducer. In this paper, static pressure distribution of inducer was examined in non-cavitation and cavitation conditions. As cavitation came, the rising curve of static pressure in front of inducer was lightened because blade lodging did. In result, this offered the mechanism that recirculation zone could be small in case that recirculation was generated in low flow rate.
