function s = IdealGasMix(infile, b, c)
|
|
% IDEALGASMIX Create a mixture of ideal gases.
|
|
% s = IdealGasMix(infile, b, c)
|
|
% Create a :mat:func:`Solution` instance representing an ideal gas mixture. ::
|
|
%
|
|
% gas1 = IdealGasMix('ctml_file'[,'transport_model'])
|
|
% gas2 = IdealGasMix('ck_file'[,'thermo_db'[,'tran_db'[,'transport_model']]])
|
|
%
|
|
% creates an object that represents an ideal gas mixture. The
|
|
% species in the mixture, their properties, and the reactions among
|
|
% the species, if any, are specified in file 'ctml_file' and 'ck_file'. Two
|
|
% input file formats are supported - CTML and CK
|
|
% (CHEMKIN-compatible). Examples::
|
|
%
|
|
% g1a = IdealGasMix('mech.xml')
|
|
% g1b = IdealGasMix('mech.xml', 'Multi')
|
|
% g2 = IdealGasMix('mech2.inp')
|
|
% g3 = IdealGasMix('mech3.inp', 'therm.dat')
|
|
% g4 = IdealGasMix('mech4.inp', 'therm.dat', 'tran.dat')
|
|
%
|
|
% Objects ``g1a`` and ``g1b`` are created from a CTML file. CTML files
|
|
% contain all data required to build the object, and do not require
|
|
% any additional database files. Objects ``g2`` - ``g4`` are created
|
|
% from CK-format input files. For ``g2``, 'mech2.inp' contains all required
|
|
% species thermo data. File 'mech3.inp' is missing some or all
|
|
% species thermo data, and requires database file 'therm.dat.'
|
|
% Object ``g4`` is created including transport data.
|
|
%
|
|
% Note that calling :mat:func:`IdealGasMix` with a CK-format input file
|
|
% also creates an equivalent CTML file that may be used in future
|
|
% calls. If the initial call includes a transport database, then
|
|
% the CTML file will contain transport data.
|
|
%
|
|

|
% thermodynamic database, if required.
