Abstract
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)

    OBSERVATION OF PASSIVE BROADBAND SUPPRESSION OF LOW-FREQUENCY UNDERWATER SOUND 

    McMellon, Evan J. (Monterey, CA; Naval Postgraduate School, 2020-12);
    We develop a proof-of-principle experiment for a recent theory published by Godin and Baynes, who showed that passive, broadband suppression of underwater sound can occur when a balloon or bladder filled with air is near ...

    Failure mechanisms in superplastic AA5083 materials 

    Kulas, Mary-Anne; Green, W. Paul; Taleff, Eric M.; Krajewski, Paul E.; McNelley, Terry R. (2006);
    The mechanisms of tensile failure in four 5083 aluminum sheet materials are evaluated under conditions of interest for superplastic and quick-plastic forming. Two mechanisms are shown to control failure of the AA5083 ...

    Experimental investigation of ventilated cavities. 

    Kinnear, Richard James (Massachusetts Institute of Technology, 1968-05);
    A wedge with a 3.5 inch chord and a half-angle of 4.1 degrees is tested in the MIT Propeller Tunnel. No pulsations were observed on the cavity. Thus, the attempt to verify the theory that pulsations are possible in an ...
