This presentation follows earlier work on the simultaneous estimation of the thermal conductivity components and heat capacity of orthotropic materials. The original innovation lays in demonstrating the feasibility of performing an experiment capable of simultaneously visualizing, using a single infrared camera, four faces of the same parallelepiped orthotropic material: the heated surface and...
The increasing complexity of advanced materials with anisotropic thermal properties necessitates more generic and efficient methods to determine three-dimensional (3D) anisotropic thermal conductivity tensors with up to six independent components. Current methods rely on a vector-based framework that can handle only up to four independent components, often leading to inefficiencies and...
Porosity in Laser Powder Bed Fusion (L-PBF) aluminium alloys strongly influences heat diffusion mechanisms and, in turn, the mechanical behaviour of additively manufactured components. This motivates the development of non-destructive approaches capable of probing porosity through thermophysically meaningful quantities. This study presents a preliminary investigation on the use of thermal...
A preliminary, purely numerical study is presented aimed at exploring the potential of a single-laser-spot thermography experiment for multi-parameter thermal characterization. The underlying idea is that localized continuous-wave laser excitation generates a temperature response whose different temporal regimes are governed by distinct physical mechanisms. In particular, the early transient...
In the context of climate change, reducing greenhouse gas emissions is necessary to achieve carbon neutrality by 2050. This requires action on several fronts: industrial decarbonisation, production of new heat sources, energy storage, solar fuel production, etc.
Solar fuels refer to molecules of interest synthesised using solar radiation as an energy source. These molecules are varied and...
Monitoring of the absorption of microwaves in water-laden food is commonly established with thermal imaging, the potential of using thermography for visualizing electromagnetic concentration in resonant aqueous objects has largely been overlooked. Water exhibits a remarkably high refractive index on the order of n~9 at household microwave frequencies of 2.5 GHz. In these systems, the...
