In some of them an additional requirement appears, as the measurement has to be made along the three perpendicular space axes. In the present article, three thermal conductivities that appear in orthotropic materials were predicted by solving an inverse heat transfer problem. This inverse problem was solved using the Cuckoo algorithm, the deterministic Levenberg-Marquardt, and with the new hybrid of these two. It was found that these three strategies produce excellent results when compared to each other. Nevertheless, the hybrid algorithm proved to be more efficient than its precursors in solving the present problem. The hybrid algorithm consumed in average less computing time compared to the metaheuristic algorithm and extended the search range in comparison to the deterministic one, always maintaining precision in its results. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49657889018 https://www.redalyc.org/journal/496/49657889018/ https://www.redalyc.org/journal/496/49657889018/html/ https://www.redalyc.org/journal/496/49657889018/49657889018.epub https://www.redalyc.org/journal/496/49657889018/movil 10.15446/dyna.v85n205.68026 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.205 Vol.85 |
