Description
Summary:The method of the inversion of linear distributed dynamic systems is developed which allows one to conduct a qualitative study and to obtain an analytical solution of a certain class of inverse heat conduction problems. As an illustration of the general approach, the inverse problem of recovering the time-varying component of an internal heat source is considered. On développe la méthode d'inversion des systèmes dynamiques linéaires distribués qui fournit une solution analytique d'une certaine classe de problèmes inverses de conduction thermique. Comme illustration de l'approche générale, on considère le problème inverse de récupération de la composante variable au cours du temps d'une source interne de chaleur. Das verfahren der inversion linear verteilter dynamischer Systeme wird entwickelt. Hiermit ist es möglich, eine bestimmte Klasse inverser Wärmeleitprobleme qualitativ zu untersuchen und analytisch zu lösen. Beispielhaft wird das allgemeine Vorgehen anhand der Ermittlung der zeitlich veränderlichen Komponente einer inneren Wärmequelle gezeigt.
