ESDU 76008 gives graphs that enable the increment in drag to be predicted for either a single or double row of rivet heads transverse to the free-stream or for an isolated rivet head. The data on which the correlations are based were obtained from wind-tunnel tests of rivet heads of height to diameter ratios between 0.2 and 0.5 for Mach numbers less than 0.5 and of rivet heads of height to diameter ratio of 0.2 only at Mach numbers of 0.8, 1.4 and 2.2. The rivet heads were mounted on a flat plate at zero incidence and the rivet head height to boundary layer thickness varied between about 0.05 and 0.35.
