Titre: Photon tunneling heat transfer in particulate system: physical characteristics and homogenization theory Résumé Radiative transfer equation (RTE) is the commonly accepted continuum scale governing equation for radiative heat transfer in particulate system. However, its applicability is questionable for non-random, densely and regularly packed particulate systems, due to dependent scattering…

Titre: Towards trustworthy use of scientific machine-learning in large-scale numerical simulations Résumé Recently, scientific machine learning (SciML) has expanded the capabilities of traditional numerical approaches by simplifying computational modeling and providing cost-effective surrogates. However, SciML models suffer from the absence of explicit error control, a computationally intensive training phase, and…
