Cylinders and spheres are considered bluff bodies because at large Reynolds numbers the drag is dominated by the pressure losses in the wake. The variation of the drag coefficient with Reynolds number ...

Turbulent Flow When the flow is turbulent, the flow contains eddying motions of all sizes, and a large part of the mechanical energy in the flow goes into the formation of these eddies which ...

For a given speed, the higher the drag coefficient is, the more drag an object feels. It turns out that a soccer ball’s drag coefficient is approximately 2.5 times larger for laminar flow than ...

These perturbations will gradually disappear in laminar flow, but if the flow is turbulent, they'll grow and produce chaotic motion. The transition, then, is the critical point between these two.

Study proves that turbulent flow can be destabilized so that it turns to an energy-saving laminar flow Date: January 8, 2018 Source: Institute of Science and Technology Austria Summary: ...

One way to make flying more ecologically efficient is to shift the change from laminar to turbulent boundary layer flow as far downstream as possible. This change from laminar to turbulent flow is ...
