Combustion gases and ideal gas mixtures
We provide property libraries for combustion gas mixtures and ideal gas mixtures:
> LibHuGas for humid combustion gas mixtures
> LibIDGAS for combustion gas mixtures according to VDI-4670
> LibIdGasMix for 25 ideal gases and their mixtures
LibHuGas
Property library LibHuGas for humid combustion gas mixtures also at high pressures, high temperatures and with high water contents.
Calculation according to the PTB-Report PTB-CP-3 as an ideal mixture of real fluids. Condensed water or desubliminated ice in a gas mixture, where present, are taken into account.
The following components of the mixtures are taken into account:
- Carbon dioxide CO2
- Carbon monoxide CO
- Sulfur dioxide SO2
- Steam, liquid water and water ice H2O
- Nitrogen dioxide N2
- Oxygen O2
- Argon Ar
- Neon Ne
LibIDGAS
Property library LibIDGAS for combustion gas mixtures according to VDI-4670.
Calculation carried out as an ideal mixture of ideal gases according to the VDI guideline 4670 for thermodynamic properties and with accurate calculation algorithms for transport properties.
The following components are considered:
- Carbon dioxide CO2
- Carbon monoxide CO
- Sulfur dioxide SO2
- Steam, liquid water and water ice H2O
- Nitrogen dioxide N2
- Oxygen O2
- Argon Ar
- Neon Ne
- Dry air
- Atmospheric nitrogen
