Flapping Membranes for Thrust Production,le membrane was 0.27. The Strouhal number (.) was varied from 0.44 to 0.16, corresponding to Reynolds numbers between 2.2x10. and 4.1 x10.. Under these conditions, a wake structure was observed that resembles the 2P structure characteristic of flapping foils but containing at least four vortex pairs

A Numerical Study on the Rectilinear Oscillations of a Circular Cylinder, Reynolds number . = 855. Numerical results are obtained over broad ranges of two externally specified parameters, i.e. the frequency of forced oscillation . relative to the natural vortex-shedding frequency .. (0.5 ≤ . / .. ≤ 4.0) and the angle of inclination η between oscillation axis and free-str

Correlation Length and Force Phasing of a Rigid Cylinder Subject to VIV,induced vibrations (VIV). We investigate different nominal reduced velocities near or in the region of maximum amplitude response for a small mass ratio and zero structural damping. We compute the correlation length of the flow quantities in the near wake and relate it to the force correlations alon

High Mode Number VIV Experiments,ttom end. The maximum achievable mode number, while towing in still water, is shown to depend primarily on mass ratio, length to diameter ratio and the maximum allowable angle of departure from vertical at the top end. Modal overlap in lock-in regions is shown to depend strongly on mass ratio in uni
