- W2318759216 abstract "Thrust performance and wake structure were investigated for a rigid rectangular panel pitching about its leading edge in a free stream. Thrust coe!cien t was found to depend primarily on Strouhal number St and the aspect ratio of the panel S/C. Propulsive e!ciency was sensitive to aspect ratio only for S/C less than 0.83; however, the magnitude of the peak e!ciency of a given panel with variation in Strouhal number varied inversely with the amplitude to span ratio A/S, while the Strouhal number of optimum e!ciency increased with increasing A/S. Peak e!ciencies between 9% and 21% were measured. Wake structures corresponding to a subset of the thrust measurements were investigated using dye visualization and Digital Particle Image Velocimetry. In general, the wakes divided into two oblique jets; however, when operating at or near peak e!ciency , the near wake in many cases represented a von K´´ vortex street with the signs of the vortices reversed. The three-dimensional structure of the wakes were investigated in detail for S/C = 0.54, A/S = 0.31, ReC = 640. Three distinct wake structures were observed with variation in Strouhal number. For approximately 0.20 0.25, a reorganization of some of the spanwise vorticity yielded a bifurcating wake formed by trains of vortex rings connected to the tips of the horseshoes. For St > 0.5 an additional structure formed from a perturbation of the streamwise leg which caused a spanwise expansion. The wake model paradigm established here is consistent with structures observed for a wide variety of unsteady flows." @default.
