Abstract

An inverse analysis utilizing the conjugate gradient method of minimization and adjoint equation is used successfully to solve the inverse problem in estimating the temperature dependent thermal conductivity of a composite material. No prior information is available on the functional form of the unknown thermal conductivity in the present study, thus, it is classified as the function estimation in inverse calculation. The accuracy of the inverse analysis is examined by using the simulated exact and inexact measurements that were obtained within the medium. Results show that an excellent estimation on the thermal conductivity can be obtained within a very short CPU time in VAX-9420 computer with any arbitrary initial guesses by using just boundary measurements (including the boundaries between different materials). The advantages of applying the present algorithm in inverse analysis can greatly simplify the experimental set up, diminish the sensitivity to the measurement errors and reduce the CPU time in inverse calculation, while the reliable predictions can still be achieved.
