Low reynolds number flow around tori of different slenderness Γ

Abstract

We present the results of axisymmetric and three-dimensional numerical simulations of the flow around a torus in the low Reynolds number regime [10-2; 3 × 103] and aspect-ratio 0 < G{cyrillic} ≤ 2, several different regimes have been observed; the peculiarities of each regime are analyzed and, whenever possible, similarities and differences with other classical flows are discussed.
