Techniques for detailed heat transfer measurements in cold supersonic blowdown tunnels using thermochromic liquid crystals

Abstract:

The paper presents methods for measurement of convective heat transfer distributions in a "cold flow" supersonic blowdown wind tunnel. The techniques involve use of the difference between model surface temperature and adiabatic wall temperature as the driving temperature difference for heat transfer and no active heating or cooling of the test gas or model is required. Thermochromic liquid crystals are used for surface temperature indication and results presented from experiments in a Mach 3 ...
