To determine heat transfer coefficients on a surface, an inverse task is used that requires either measured surface temperature history or, more often, measured temperature history inside the body. To measure temperature inside the body, a thermocouple must be placed inside. The installed thermocouple disturbs the homogeneity of the temperature profile and thus the measured temperature is different from the original one. This paper describes an experiment and a computational method for determination of heat resistances between the thermocouple and the body. Comparison of computed heat transfer coefficients for the fixed model and for a model that ignores installed thermocouple is made.
