Comparison of measured and theoretical pressure distribution on a NACA 0015 foil
Grahic Jump Location
Mapping of cavitation regimes. The lines l/c=constant are obtained from a linear fit to the cavity length data in Fig. 5.
Grahic Jump Location
JFTA of suction side pressure transducer at 7 degrees angle of attack. The intensity of the color denotes the amplitude. St≡fc/U.
Grahic Jump Location
Composite plot of type I peak frequency obtained at various angles of attack
Grahic Jump Location
Average and dynamic characteristics of lift and pressure difference have been found to correlate well with each other. The abscissa of the power spectra is in Strouhal number, fc/U.
Grahic Jump Location
Mean velocity comparison with and without cavitation. y=0 is taken to be that of maximum velocity deficit for the noncavitating case. (a) Measured data. (b) Numerical simulations of Song and He.
Grahic Jump Location
Comparison of lift dynamics with the FFT of data rate in a cavitating flow. The fundamental frequency corresponds to a Strouhal number, fc/U=0.15.
Grahic Jump Location
Numerical simulations of cavitating flow. Shown is the variation over one cycle of oscillation. Shading denotes vorticity, with dark black being positive.
