Solution of an inverse thermal problem. Application to the determination of parietal temperature fluctuations; Resolution d`un probleme thermique inverse. Application a la determination des fluctuations thermiques parietales

Abstract

Solution of an inverse heat conduction problem (estimation of parietal temperature fluctuations inside a pipe from external measurements) using transfer functions is proposed. An analytical method and impulse response technique are studied, compared and tested for a PWR pipe, in working conditions favourable to thermal striping. The study shows the advantages of thermal stress measurements in comparison with temperature measurements for a better efficiency of the inverse method and gives proof of the better suitability of the impulse response technique for complex geometries. (authors). 5 figs., 12 refs.
