Determination of boundary-layer transition Reynolds numbers by surface-temperature measurements of a 10 degree cone in various NACA supersonic wind tunnels

One of 4,120 reports in the series: NACA Technical Notes available on this site.

PDF Version Also Available for Download.

Description

Report presenting an investigation in several NACA wind tunnels to determine transition Reynolds numbers on a 10 degree cone at zero angle of attack. The trends of transition Reynolds number with stream Reynolds number and Mach number are not consistent across the different tunnels. These inconsistencies are attributed to variations in free-stream turbulence, flow irregularities introduced by compressor systems, and other airstream disturbances like compression- or expansion-wave boundary-layer interactions.

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
