Theory of Wing Sections, Including a Summary of Airfoil Data
Ira Herbert Abbott. of minimum drag coefficient with Reynolds number for several
wing sections is shown in Fig. 66. The drag coefficient generally decreases with
increasing Reynolds number up to Reynolds numbers of the order of 20 million.
We assume that the drag coefficient (23) can be expressed as the sum of a
frictional-drag coefficient, depending on the Reynolds number, plus a residual-
drag coefficient which now must depend on the Froude number. Thus, we adopt ...

Wind Loading of Structures
The effect of aspect ratios less than 20 is significant on the effective total drag
coefficient (see Figures 4.10 and 4.19). Other cross-sections may require wind-
tunnel tests to determine drag coefficients. The mean or time-averaged drag force
per ...

Engineering Fluid Mechanics
The corresponding result for drag coefficient of a circular cylinder is CD = 87t(1 -
0.87/S2)/S Re, Re < 1, (7.5.4) where S = -0.07721+ In (8/Re). Here the Reynolds
number is based on the cylinder diameter. This result was found byS.
The sharp drop off of the drag coefficient at Re ≈ 3 · 105 is due to the transition of
the previous laminar boundary layer on the sphere to a turbulent boundary layer.
The shear stresses in the turbulent boundary layer are larger, and the outer ...

Multiphase Flows with Droplets and Particles
There is reason to doubt their validity in that they predict a drag coefficient of 0.48
for a Reynolds number of 500 and relative turbulence intensity of 0.07. This is
less than the standard drag coefficient for a sphere at this Reynolds number.

Debris Forces on Highway Bridges
Hsieh (1964), using cylindrical model piers, found that the Froude number of the
flow, as well as boundary geometry, influences the drag coefficient for cylindrical
piers. He also found that the drag coefficient decreased with increase in depth ...
