This paper presents a multi-domain acoustic topology optimization methodology applied to the design of reactive and dissipative expansion chamber mufflers. Based on the Bi-directional Evolutionary Structural Optimization (BESO) algorithm, the proposed approach also uses a novel material interpolation scheme that considers acoustic, porous and rigid domains during the optimization process, hence configuring a multi-phase procedure. Furthemore, more than one muffler per BESO iteration is considered, being also possible to optimize for specific frequency bands in predefined chambers.

This work details a new acoustic topology optimization methodology with applications on the design of systems composed of rigid and porous materials. The Bi-directional Evolutionary Structural Optimization (BESO) algorithm is combined with the Virtual Temperature Method to minimize the occurrence of air cavities and rough surfaces inside rigid and porous domains, hence configuring a multiconstrained optimization approach.
