Rainbow trout provide the first experimental evidence for adherence to a distinct Strouhal number during animal oscillatory propulsion.
The relationship between tail (or wing) beat frequency (f(tail)), amplitude (A) and forward velocity (U) in animals using oscillatory propulsion, when moving at a constant cruising speed, converges upon an optimum range of the Strouhal number (St = f(tail) · A/U). Previous work, based on observational data and supported by theory, shows St falling within the broad optimum range (0.2<St<0.4) and...
متن کاملAn investigation of a low Strouhal number oscillatory jet submerged in a thin rectangular cavity
Laser Doppler anemometry (LDA) and cinematic particle image velocimetry (PIV) measurements of a low Strouhal number oscillatory jet are compared to two-dimensional computational fluid dynamic (CFD) model predictions. The LDA and PIV measurements are recorded from a water model consisting of a jet generated from a submerged entry nozzle (SEN) immersed in a rectangular cavity. The cavity has a wi...
متن کاملTesting Experimental Subunit Furunculosis Vaccines for Rainbow Trout
11 Aeromonas salmonicida subsp. salmonicida (AS) is the etiological agent of typical furunculosis in salmonid 12 fish. The disease causes bacterial septicemia and is a major fish health problem in salmonid aquaculture 13 worldwide, inducing high morbidity and mortality. In this study we vaccinated rainbow trout with subunit 14 vaccines containing protein antigens that were selected based on an ...
متن کاملStrouhal-Reynolds number relationship for vortex streets.
A rationale for the empirically observed Strouhal-Reynolds number relation for vortex shedding in the wake of a cylinder is provided. This rationale derives from a mechanism of vortex formation observed in numerical simulations of two-dimensional vortex shedding coupled with an order of magnitude estimate of the terms in the vorticity transport equation based on this mechanism.
