Boundary flux reconstruction for narrow band TLC applications E. Divo & A. J. Kassab Mechanical, Materials, and Aerospace Engineering Department University of Central Florida Orlando, Florida, 32816-2450, USA Abstract The BEM and a genetic algorithm are used to solve the so-called "time-to- arrival" problem in which an unknown surface heat flux is reconstructed given limited temporal information regarding the surface temperature evolution. 1. Introduction In this paper, we propose to solve an inverse problem which can be construed as reconstructing the heat flux at a surface given information of the time it took for a measuring point to reach a characteristic temperature. This problem can thus be termed the time-to-arrival problem. The application for which this inverse problem is formulated arises in the use of narrow-band Thermochromic Liquid Crystal (TLC) [1] or Phase Change Materials (PCM) coatings thermography where the coating material responds at a characteristic te
