bloc.chem.thermo#

Gas-phase composition helpers (solid carbon removal).

Functions#

`get_gas_phase_composition`(gas[, solid_sp, n_C_min])	Return the gas phase composition by removing solid species and renormalising the mole/mass fractions.
`get_gas_species`(gas[, solid_sp, n_C_min])	Return a list of gaseous species from the gas object.
`get_gas_phase_density`(gas[, solid_sp, n_C_min])	Return the corrected density of the gas object, removing the solid species.
`get_STP_properties_IUPAC`(g)	Get density and enthalpy under Standard Temperature & Pressure (STP).
`get_NTP_properties_NIST`(g)	Get density and enthalpy under Normal Temperature & Pressure (NTP).
`get_DIN1343_properties`(g)	Get density and enthalpy under Normal conditions according to DIN 1343.
`heating_values`(fuel[, mechanism, return_unit, verbose])	Return the Lower & Higher heating values (LHV, HHV) for the specified fuel, in J/kg.

bloc.chem.thermo.get_gas_phase_composition(gas, solid_sp=['C(s)', 'C(soot)', 'CSOLID'], n_C_min=300)#

Return the gas phase composition by removing solid species and renormalising the mole/mass fractions.

Parameters:

gas (cantera.Solution) – The gas phase object from Cantera.
solid_sp (list of str, optional) – List of solid species to remove from the gas phase composition. Default is [“C(s)”, “C(soot)”, “CSOLID”].
n_C_min (int, optional) – Minimum number of carbon atoms to consider a species as solid. Default is 300.

Returns:

The gas phase composition by removing solid species and renormalising the mole/mass fractions.

Return type:

cantera.Solution

bloc.chem.thermo.get_gas_species(gas, solid_sp=['C(s)', 'C(soot)', 'CSOLID'], n_C_min=300)#

Return a list of gaseous species from the gas object.

Parameters:

gas (cantera.Solution) – The gas object containing gaseous species and soot.
solid_sp (list of str, optional) – List of solid species to consider. Default is [“C(s)”, “C(soot)”, “CSOLID”].
n_C_min (int, optional) – Minimum number of carbon atoms to consider a species as solid. Default is 300. This is used as a second filter to identify solid carbon species. A specie is considered solid if it satisfies one criterium (s in solid_sp) OR the other (n_C >= n_C_min).

Returns:

A list of gaseous species names (i.e., not solid carbon species).

Return type:

list of str

bloc.chem.thermo.get_gas_phase_density(gas, solid_sp=['C(s)', 'C(soot)', 'CSOLID'], n_C_min=300)#

Return the corrected density of the gas object, removing the solid species.

Parameters:

gas (cantera.Solution) – The gas object containing gaseous species and soot. Works with states[i].
solid_sp (list of str, optional) – List of solid species to consider. Default is [“C(s)”, “C(soot)”, “CSOLID”].
n_C_min (int, optional) – Minimum number of carbon atoms to consider a species as solid. Default is 300. This is used as a second filter to identify solid carbon species. A specie is considered solid if it satisfies one criterium (s in solid_sp) OR the other (n_C >= n_C_min).

Returns:

The corrected density of the gas object, removing the solid species.

Return type:

float

bloc.chem.thermo.get_STP_properties_IUPAC(g)#

Get density and enthalpy under Standard Temperature & Pressure (STP).

Here STP is defined as :

It should not be confused with :

0°C (273.15 K), 1 atm (101.325 kPa): as in STP by IUPAC (before 1982) and as in
DIN 1343, used as the base value for defining the standard cubic meter.
15°C (288.15 K), 1 atm (101.325 kPa): as in ISO 2533 conditions
20°C (293.15 K), 1 atm (101.325 kPa), as in Normal (NTP) conditions by NIST
