Summary

A HIGH SENSITIVITY, FAST RESPONSE HEAT FLUX SENSOR WAS DEVELOPED FOR HEAT FLUX MEASUREMENT AT A MOVING SURFACE SUBJECTED TO RAPIDLY FLUCTUATING HEAT FLUX. THE SENSOR IS A GOLD THIN FILM RESISTANCE THERMOMETER ON A NON-CONDUCTING SUBSTRATE. MOUNTED FLUSH WITH THE MOVING SURFACE, THE SENSOR MEASURES INSTANTANEOUS SURFACE TEMPERATURE WITH A RESOLUTION OF ABOUT 0.002 K AT SAMPLING SPEEDS UP TO 5,000 PER SECOND. LOCAL HEAT FLUX IS OBTAINED THROUGH SOLUTION OF THE UNSTEADY HEAT CONDUCTION EQUATION. HEAT TRANSFER PROFILES ARE GENERATED WITH THIS TECHNIQUE FOR THE CASE OF PLANE JETS IMPINGING ON SURFACES MOVING AT SPEEDS UP TO 12 M/S.
