Abstract

An interesting example of quantitative exploitation of infrared thermographic measurements in the study of Inverse Heat Conduction Problems (IHCP) is presented. An original method, based upon a Boundary Element formulation and numerical techniques of regularization, is proposed to solve such a problem in the stationary case. Finally an application example is described : the determination of the flux density acting on the hidden side of a thermal system by using infrared thermographic measurements on its visible side.
