epsilonm is obtained by combining epsilon.gas and epsilon.liquid in a two-phase
system, each of which will apply the epsilonWallFunction at walls; the
epsilonmWallFunction propagates the resulting wall epsilonm into the near-wall
cells.
If the 0/epsilonm file is provided the epsilonmWallFunction should be specified
for walls, if the 0/epsilonm file is not provided it will be generated
automatically and the epsilonmWallFunction applied to walls for which the
epsilonWallFunction is specified in the epsilon.liquid file.
The FOAM file format has not changed from version 2.0 in many years and so there
is no longer a need for the 'version' entry in the FoamFile header to be
required and to reduce unnecessary clutter it is now optional, defaulting to the
current file format 2.0.
The new multiphaseEulerFoam is based on reactingMultiphaseEulerFoam with some
improvements and rationalisation to assist maintenance and further development.
The phase system solution has been enhanced to handle two phases more
effectively and all two-phase specific models updated for compatibility so that
multiphaseEulerFoam can also replace reactingTwoPhaseEulerFoam.
When running multiphaseEulerFoam with only two-phases the default behaviour is
to solve for both phase-fractions but optionally a reference phase can be
specified so that only the other phase-fraction is solved, providing better
compatibility with the behaviour of reactingTwoPhaseEulerFoam.
All reactingMultiphaseEulerFoam and reactingTwoPhaseEulerFoam tutorials have
been updated for multiphaseEulerFoam.
