Hydrodynamic drag versus roughness for rotating disks

Stylus measurements of the microroughness of rotating disks and their significant correlation with hydrodynamic drag measurements were studied. The roughest disks ( R a ≈ 16 μm) were found to have drag coefficients about 30% greater than those of the smoothest disks ( R a ≈ 0.14 μm). For a Reynolds&...
