A new version of AeroSolved, a computational fluid dynamics (CFD) solution for aerosol simulations, has been released on the open-source GitHub platform. The freely available software models the complex dynamics of aerosol mixtures from their generation through evolution, transport, and deposition. AeroSolved can be used for the development, characterization, and assessment of inhalation devices, aerosol generators, and aerosol delivery systems. It can also be applied in an industrial context to support the reduction of emissions, as well as in other aspects of environmental and atmospheric science.

“Until now, publicly available CFD tools were limited in their ability to effectively model the wide range of physical processes involved in the multi-phase interactions of complex aerosol mixtures,” said Arkadiusz Kuczaj, Associate Professor, Industrial Computational Modeling, University of Twente, The Netherlands, and Manager, Aerosol Research and Dosimetry, PMI. “AeroSolved combines advanced techniques in physics modeling, mathematical representation, and computational processing to deliver cutting-edge aerosol simulations robust enough for a range of industrial applications. Crucially, AeroSolved is embedded in and compatible with OpenFOAM, an existing, widely used open-source CFD platform, allowing users to take advantage of extensive, highly developed libraries in their simulations.”

AeroSolved is able to simulate aerosol mixtures across gas, liquid, and solid phases. Modeling takes into account mass transfer, aerosol particle size distribution, particle velocity, and phase-coupled thermodynamic properties of aerosol mixtures (e.g. viscosity, heat capacity, heat conductivity, and surface tension). It offers modeling of aerosol nucleation (formation of particles), coagulation, condensation, and evaporation of liquid mixtures. It can also be used to assess the deposition of aerosol mixtures on surfaces by modeling impaction, sedimentation, and diffusion processes. By taking advantage of OpenFOAM’s extensive physics and chemistry modeling libraries, the computational power of AeroSolved offers new possibilities in the exploration of the complex processes of aerosol physics.
