IHS ESDU Extrapolating wind-tunnel data to full-scale Reynolds number Part 2: Procedures 07010

ESDU 07010 outlines procedures used in transonic wind-tunnel testing to facilitate the extrapolation of wind-tunnel data to full-scale Reynolds number."Aft fixing" (in which transition is artificially imposed downstream of the anticipated full-scale location) improves the modelling of important features (such as the interaction of a shock wave with the boundary layer) and its use is described in detail. Limitations of the aft-fixing technique are emphasized, as are the specific considerations relating to particular test objectives.
