ABSTRACT
This paper describes a numerical method developed to estimate the
heat flux at the surface of a solid, using temperature measurements
inside it. This inverse problem is solved while taking advantage of the
available analytical solution of the direct problem. Moreover, the
efficiency of the proposed algorithm appears when analysing several
measurements because most of the calculations are made only once
for all the records.
INTRODUCTION
During a current interruption process in a circuit-breaker, the energy
dissipated in the electric arc is transmitted to the surrounding media
(quenching gas, insulating nozzle, metallic contacts, ...). Specifically
this paper deals with the problem of estimating the heat flux flowing
from the arc column to the electrodes : this information is indeed very
important to charac
