Abstract

A centrifugal compressor according to an embodiment includes a compressor impeller, a compressor housing, a suction-surface-side member disposed on a suction surface side of the compressor impeller, and a piezoelectric vibrator disposed in at least one of the compressor housing or the suction-surface-side member. The compressor housing and the suction-surface-side member have wall surfaces defining a space surrounded by the compressor housing and the suction-surface-side member. The wall surface of the at least one of the compressor housing or the suction-surface-side member is at least partially vibratable by operation of the piezoelectric vibrator.
