Investigation of Turbulence in Wind Tunnels by a Study of the Flow About Cylinders (1926)
NASA Technical Reports Server (NTRS) · leaf 7
R AEEONAUTICS RESULTS OF TESTS The results are expressed in the form of nondimensional coefficients plotted against the common logarithm of the Reynolds number. The coefficient is defined by the relation D =CSa I 1 g °nt, Thnder' S Pr°duCt °f CyHnder diameter ^ the length exposed to the wind… … Airspeed, ft/sec. Fig. 2—Resistance of M-inch cylinder, open tunnel The curves shown in Figures 4, 5, 6, and 7 are each computed from average curves repre- senting the force measurements plotted against wind speed. A typical curve of this type is shown in Figure 2", JEach observation has been…
