WebThe flow could still remain turbulent, just less so. Here are a few ways to do this discussed by this review article: dissipation of turbulence (could happen from enlargement in a pipe) curved or rotating flows (could introduce swirl, though) acceleration (could happen from a contraction in a pipe) There are a number of papers on suppression of ... Web21 nov. 2024 · The speed at which a fluid flows past an object varies according to how far from the object you are. If you're sitting in a parked car and a gale-force wind is howling past you at 200km/h (125mph), you might think the difference in speed between the air and the car is 200km/h—and it is! dwht56141
