Foam materials are frequently used in engineering applications, due to their absorption and sound insulation properties. At the same time, the evolution of CO2 emission goals, together with new standards for acoustic, thermal, and fire resistance performance, calls for further developments that seek to reduce the impact of acoustic treatments---while maintaining, or even improving, global performance. Fine particles are usually introduced during the foaming process to improve fire resistance. By disrupting the nucleation sites, this procedure leads to disordered microstructures where cells of very different sizes coexist locally. This thesis work deals with the construction and experimental validation of a computational multi-scale-informed...
