In addition to blade surface cavitation, tip leakage and backflow cavitations occur in real inducers. Although most of cavitation instabilities can be explained by considering only blade surface cavitation, these types of cavitation might play an important role especially for the suppression of instabilities. Those cavitations are three-dimensional in its nature and this makes it difficult to analyze them theoretically even without cavitation. Under this situation not much is known about these cavitation types. In this document, research efforts into unsteady characteristics of those cavitation types are described, although they are by no means complete as yet.
