WebJul 27, 2009 · Analysis of the flow and density fields shows that the added drag results from the buoyancy of the fluid in a region of size (ν/ N) 1/2 surrounding the sphere, while the bulk of the wake does not influence drag. A scaling argument is … WebIn fluid dynamics, drag (sometimes called fluid resistance) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface.. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag …
