High drag coefficient
WebAnswer (1 of 2): It’s all about delaying the onset of flow separation and wake drag. Turbulent flow stays attached longer and reduces drag (why golf balls gave dimples). If you can minimize the wake then laminar is better, in most cases you have to live with the wake so you want to delay onset as...

Web1 de abr. de 2003 · By determining surface stress, roughness length and neutral stability drag coefficient, we find that surface momentum flux levels off as the wind speeds increase above hurricane force. Web3.2 Drag Coefficient, C d Fluid dynamics, the drag coefficient (commonly denoted as C d) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the

In reality the influence of the wing fades the more you move away from it. This picture of a stream tube is a simplification which you will also find in propeller theory , and it gives the correct result, because what you neglect in the far field you compensate by assuming a …
