WebJul 31, 2010 · A passive flow control on a generic car model was experimentally studied. This control consists of a deflector placed on the upper edge of the model rear window. The study was carried out in a wind tunnel at Reynolds numbers based on the model height of 3.1 × 105 and 7.7 × 105. The flow was investigated via standard and stereoscopic … WebMay 22, 2024 · • A bluff body is defined as that body whose surface is not aligned with the stream-lines, when placed in the flow. • Thus, the body offers lesser resistance in terms …
Bluff Body Overflow and Drag Reduction Control
In fluid dynamics, the drag equation is a formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The equation is: • is the drag force, which is by definition the force component in the direction of the flow velocity, • is the mass density of the fluid, WebApr 21, 2024 · In this study drag and liftcoefficient and pressure distribution on a bluff body i.e. wooden flat plate 200 mm x 200 mm x 25 Thick is tested in a subsonic wind tunnel. The wooden plate is tested ... kintec orthotics cost

WebSep 1, 1999 · The shielding effect of square-plate and D-shaped front bodies on the drag reduction and the pressure distribution of a three-dimensional bluff body is investigated. Streamlining a bluff or an otherwise unstreamlined body shape is a very effective technique for reducing drag. For example, the basic idea is shown in the figure below. Adding a tail and/or nose fairing can delay or even eliminate flow separation, streamlining the resulting flow and reducing the drag. While … See more Another effect experienced by golf balls, as well as other balls used for numerous games and sports, is a lift force produced by its spinning … See more The flows that are produced about more general three-dimensional bluff body shapes are considerably more complex, and some of the other types of flow phenomena involved are shown in the figure below, which … See more As would be expected, the aerodynamic drag of terrestrial vehicles such as automobiles, trucks, and trains, increases significantly at higher speeds. For a given drag coefficient, , then the drag, , on the vehicle will increase … See more WebJan 1, 2013 · The aerodynamic characteristics of bluff bodies differ substantially from streamlined bodies, and an understanding of bluff body aerodynamics is essential to make progress in understanding wind … lynne bloxham twitter
