Abstract

We present a BEM-based inverse algorithm to retrieve multi-dimensional heat transfer coefficients (h) from surface temperature measurements. The time history of temperatures at convective BEM nodes is measured (or simulated). At each time level, a regularized least-squares functional is minimized to retrieve current fluxes and simultaneously smooth out temperature measurement errors. The regularization term weighs the square of deviations of BEM-computed fluxes from a mean flux to allow adjustment of temperatures and fluxes to obtain a "be
