This allows single, multi-phase and VoF compressible simulations to be performed
with the accurate thermophysical property functions for liquids provided by the
liquidProperty classes. e.g. in the
multiphase/compressibleInterFoam/laminar/depthCharge2D tutorial water can now be
specified by
thermoType
{
type heRhoThermo;
mixture pureMixture;
properties liquid;
energy sensibleInternalEnergy;
}
mixture
{
H2O;
}
as an alternative to the previous less accurate representation defined by
thermoType
{
type heRhoThermo;
mixture pureMixture;
transport const;
thermo hConst;
equationOfState perfectFluid;
specie specie;
energy sensibleInternalEnergy;
}
mixture
{
specie
{
molWeight 18.0;
}
equationOfState
{
R 3000;
rho0 1027;
}
thermodynamics
{
Cp 4195;
Hf 0;
}
transport
{
mu 3.645e-4;
Pr 2.289;
}
}
However the increase in accuracy of the new simpler and more convenient
specification and representation comes at a cost: the NSRDS functions used by
the liquidProperties classes are relatively expensive to evaluate and the
depthCharge2D case takes ~14% longer to run.

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
