Simulation-Based Optimization, Heat Transfer, Radiative Transfer, Uncertainty QuantificationAbstract
The photothermal effect due to surface plasmon resonance has several interesting
applications in fields such as optoelectronics, photonics, and nanotechnology. However, its use raises
the analysis of the multiphysics of coupled thermal-radiative problems of great complexity, both in
theoretical and computational terms, which can only be approximately resolved. This work
investigates the uncertainty quantification arising from modeling errors in an equivalent thermal
source for a coupled remote heating problem, on a nanocomposite with gold nanoparticles. As a
starting point, a simplified model for an infinite one-dimensional bar is explored and its practical
scope is studied, before focusing the analysis on numerical results found through simulation-based
optimization. Specifically, the impact of modeling an equivalent thermal source on the temperature
profile is analyzed, with particular focus on the thermal characterization of the material. Additionally,
the sensitivity of the source to the design parameters of the nanocomposite is also studied.
