This paper provides practical data for thermal product values of different scratched temperature sensors that can be used for accurate transient heat transfer measurements under hypersonic flow conditions. The effect of using different scratch techniques (abrasive papers and scalpel blades) to form the sensor's junction is investigated. It was observed that the thermal product of a particular sensor depends on the Mach number, junction scratch technique, junction location and enthalpy conditions. It was demonstrated that using different scratched technique would produce different thermal product values. � 2010 Science Press and Institute of Engineering Thermophysics, CAS and Springer-Verlag Berlin Heidelberg.
