- Furthermore, he has contributed significantly in understanding the bluff body flows.
- In hydrodynamics, a form of horseshoe vortex forms around bluff bodies in the flowing water, for instance around bridge piers.
- Evidence that Prandtl's scenario occurs for bluff bodies in flows of high Reynolds numbers can be seen in impulsively started flows around a cylinder.
- One of the classical open-flow problems in fluid mechanics concerns the flow around a circular cylinder, or more generally, a bluff body.
- In this branch, Matsumoto et al . went further, proposing enhancements for that system and assessing the feasibility of its usage with bluff bodies.
- His work on large-eddy simulation of flow past bluff bodies and heat transfer in impinging jets have been deeply admired by the scientific community.
- In fluid mechanics a "'Riabouchinsky solid "'is a technique used for approximating boundary layer separation from a bluff body using potential flow.
- The use of Riabouchinsky solids renders d'Alembert's paradox void; the technique typically gives reasonable estimates for the drag offered by bluff bodies moving through inviscid fluids.
- This is clearly not a linear resonance phenomenon, even if the bluff body has itself linear behaviour, since the exciting force amplitude is a nonlinear force of the structural response.
- These are often bluff bodies or " vee-gutters " directly behind the fuel injectors that create localized low speed flow in the same manner the dome does in the main combustor.
- For sharp-cornered bluff bodies, like square cylinders and plates held transverse to the flow direction, this equation is applicable with the drag coefficient as a constant value when the Reynolds number is greater than 1000.
- This is because bluff bodies ( non-streamlined bodies ), like bridge decks, in a fluid stream shed wakes, whose characteristics depend on the size and shape of the body and the properties of the fluid.
- A large amount of studies and researches has been conducted concerning these interactions and their dependencies, aiming the understanding of the aerodynamic phenomena that arise due to them, such as the K�rm�n vortex street, galloping, buffeting and flutter, mainly regarding bluff bodies.
- The reference length can vary depending on the analysis to be performed : for body with circle sections such as circular cyliners or spheres, one usually chooses the diameter; for an airfoil, a generic noncircular cylinder or a bluff body or a revolution body like a fuselage or a submarine, it is usually the profile chord or the profile thickness, or some other given widths that are in fact stable design inputs; for flow channels usually the hydraulic diameter ) about which the fluid is flowing.
