MetadataShow full item record
An approximate theory for cavitation in pump impellers is developed on the basis of a one-dimensional potential flow model. The theory incorporates the unsteady term occurring in Bernoulli's equation and accounts for blockage effects due to vane thickness. A comparison of the theoretical results with experimental data from mixed flow impeller tests shows good agreement near the condition of zero incidence. On the basis of the theoretical results a mechanism of cavitation breakdown is proposed. (Author)
