The steady flow around an inclined torus has received little attention in the hydrodynamics literature, despite being relevant to many engineering and biological processes, such as the sedimentation of fluidized particles and the motion of natural micro-swimmers. In this study, we perform three-dimensional direct numerical simulations of the flow around an inclined torus over a range of aspect ratios (2 <= (sic) <= 3), inclination angles (0 <= theta <= 90 degrees) and Reynolds numbers (10 <= Re <= 50), with a focus on the steady flow regime preceding the onset of vortex shedding.
