Abstrakt

A conceptual mathematical model for an unconventional transducer that measures the time history of an applied heat flux pulse is developed. This transducer converts the heat flux impinging on its surface into a spatial distribution of maximum temperatures which are assumed to be permanently recorded in a spatial material medium in such a way that they may be retrieved. The inverse problem of the one-dimensional heat conduction equation is considered using this spatial distribution of the maximum temperatures to reconstruct the time history of the heat flux pulse. The results of this study indicate the feasibility of this kind of transducer. The need, however, for further studies, in the field of permanent temperature indicators, has to be satisfied before the actual design of such a transducer.
