Two new phase models have been added as selectable options for reactingMultiphaseEulerFoam; pureStationaryPhaseModel and pureStationaryIsothermalPhaseModel. These phases do not store a velocity and their phase fractions remain constant throughout the simulation. They are intended for use in modelling static particle beds and other forms of porous media by means of the existing Euler-Euler transfer models (drag, heat transfer, etc...). Note that this functionality has not been extended to reactingTwoPhaseEulerFoam, or the non-reacting *EulerFoam solvers. Additional maintenance work has been carried out on the phase model and phase system structure. The system can now loop over subsets of phases with specific functionality (moving, multi-component, etc...) in order to avoid testing for the existence of equations or variables in the top level solver. The mass transfer handling and it's effect on per-phase source terms has been refactored to reduce duplication. Const and non-const access to phase properties has been formalised by renaming non-const accessors with a "Ref" suffix, which is consistent with other recent developments to classes including tmp and GeometricField, among others. More sub-modelling details have been made private in order to reduce the size of interfaces and improve abstraction. This work was supported by Zhen Li, at Evonik
