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. |
