On-line indirect thermal measurement in a radiant furnace by a reduced modal model

Abstract : We propose an original method to recover the whole thermal field of a heated object on a furnace from a few measurement points. The radiant thermal source is first identified via a low order reduced model based on AROMM (Amalgam Reduced Order Modal Model) method. From this identified temperature, the thermal field is then recovered by direct simulation using a reduced model of higher order which leads to a better precision. This process is applied to a complex titanium object heated by two radiant panels placed in the furnace. From two measurement points, the temperature of the heated object is recovered on-line, with a mean error below 3K.
