Summary
Experiments in the shock tunnel TH2 have been conducted using heated ramp models with deflection angles of 15° and 24°. Surface temperatures of 700 K were reached with electrical resistance heating and 1000 K with radiation heating. The experiments showed an increase in separation length for increasing surface temperature for laminar flow. By suitable scaling, agreement can be achieved between the experimental results and theoretical approaches describing the separation length scaled with the boundary–layer thickness. The results show the independence of the ratio of separation length to boundary-layer thickness at separation on the wall-to-total-temperature ratio Tye/T o proposed by Stollery and Needham. The boundary-layer thickness was determined with pitot-rake measurements on cold surfaces.
