Digital twin of a laser flash experiment helps to assess the thermal performance of metal foams

Metal foams are a class of materials with immense potential. The complex topology in these lightweight systems is responsible for their outstanding mechanical and thermal properties. Furthermore, this the same reason why assessment metal challenging. While conventional analytical techniques provide useful data, modern-age technology allows to explore transfer great detail by building digital twin characterisation experiment. In work, high-accuracy measurements laser flash analysis instrument, processed two effective-medium heat conduction models, compared built computed tomography finite element analysis. This combination helps resolving complexity analysing AlSi7Mg open-cell foams. Evidence non-Fourier macroscopic found, which makes standard laser-flash non-scalable.
