Type of article: Article

Summary

HEAT TRANSFER FROM A < HOT > GAGE TO A < COLD > FLUID WAS MEASURED USING A GUARDED HOT-PLATE TECHNIQUE. THE SYSTEM WAS USED TO CALIBRATE GARDON-TYPE CIRCULAR FOIL HEAT FLUX G THE CALIBRATION CURVES ARE NONLINEAR, WHICHIS DIFFERENT FROM THE LINEAR CALIBRATION OBTAINED USING THE STANDARD RADIATION TECHNIQUE. THE DEGREE OF NONLINEARITY MATCHES THE ANALYSIS WHICH ACCOUNTS FOR THE EFFECT OF THE TEMPERATURE DISTRIBUTION IN THE GAGE FOIL. THE EFFECT OF THIS TEMPERATURE DISTRIBUTION CAN BE NEGLECTED IN THE STANDARD RADIATION CALIBRATION BUT IS OFTEN SIGNIFICANT IN CONVECTION APPLICATIONS.
