Grahic Jump Location
Schematic diagram of the hydrofoil section. The foil surfaces are portions of a 7:1 ellipse. The positions of the electrode pairs are shown.
Grahic Jump Location
Typical voltage traces from the electrode pairs. The voltage from the first through eighth pairs are shown over a time span of 1.4 s. The signal output scale is arbitrary, and the signals are scaled to have the same span. The cavity closure was near the 12th electrode pair.

Examples of Rx,y(τ) for a partial cavity with a mean length, the Lc/c=0.36 at σ=3 deg. Typical correlations are shown for R1,2(τ),R2,3(τ),R3,4(τ),R4,5(τ),R5,6(τ),R6,7(τ),R7,8(τ), where the subscripts represent the particular electrode pairs which were correlated. The range −0.005<τ<0.05 is shown. The mean position of cavity closure was near the fourth electrode pair.
Grahic Jump Location
The near-surface gas-phase velocity derived from cross-correlating surface electrode data for a cavity with Lc/c=0.36 at α=3 deg. The cross marks the position of mean cavity closure.
Grahic Jump Location
The near-surface gas-phase velocity derived from cross-correlating surface electrode data for a cavity with mean Lc/c=0.36 (a), 0.50 (b), 0.63 (c), and maximum Lc/c=1 (d) at α=2 deg. The cross marks the position of mean cavity closures.
