What is AeroSolved?

AeroSolved was developed to study aerosol dynamics starting from the aerosol generation through its evolution, transport, and deposition. The implemented aerosol physics is applicable to a wide range of practical applications, including the development of aerosol generators, inhalation devices, validation of aerosol delivery systems for in vivo inhalation studies and in vitro sciences as well as for atmospheric sciences. The aerosol is described within a Eulerian-Eulerian framework with the aerosol size distribution and aerosol dynamics represented by either a sectional or a two-moment method. The code is implemented on the basis of the OpenFOAM open-source software. AeroSolved was developed jointly between Philip Morris International R&D (PMI R&D) and the Department of Applied Mathematics at the University of Twente (UT), The Netherlands.

AeroSolved includes the following key capabilities:

  • Simulations of mass, momentum (Navier-Stokes equations), and energy conservation equations
  • Multispecies formulation for gas (vapor), liquid (droplet) phases and solid particles
  • Aerosol physics containing the following processes:
    • Nucleation
    • Condensation/Evaporation
    • Brownian coagulation
  • Aerosol deposition:
    • Inertial impaction
    • Sedimentation
    • Diffusion

Software download and documentation

AeroSolved is available through the AeroSolved GitHub repository, which includes a few tutorials and validation cases.

AeroSolved has been updated!

Initially, AeroSolved 1.0 was developed within the OpenFOAM 2.3.x framework, only taking into account the finite volume discretization, numerical computation, and parallelization libraries, but not relying on the OpenFOAM (physics or chemistry) modeling libraries.

AeroSolved 2.0 is OpenFOAM v18.12/19.06-compatible and fully integrated with the OpenFOAM modeling libraries. It follows the reactingFOAM solver approach for the treatment of the partial differential equations and source terms.
