Abstract
The vortex street wake of a large-aspect-ratio torus is characterised by measurements of amplitude and frequency of the velocity fluctuation s for different oblique shedding modes resulting from the periodic spa nwise boundary conditions in this geometry. The experimental data conf irm the validity of the phenomenological Ginzburg-Landau model in the entire laminar regime (Reynolds numbers between 50 and 180). The depen dence on Reynolds numbers of certain model parameters is deduced from these results.
