Impellers - an overview ScienceDirect Topics

Impellers are the components in a centrifugal compressor that perform work on the gas to be compressed. Since they are rotating parts with fairly high vane tip velocities, they are also the most highly stressed components in a centrifugal compressor. As such, impeller construction is a subject of interest.
