Shape factor of isotropic-velocity distribution for electron energy mass_fraction_dict ( threshold = 0.0 ) # Returns true if the phase represents a pure (fixed composition) substance isothermal_compressibility # The thermodynamic state of a substance is_pure # Returns true if the density of the phase is an independent variable defining Returns true if the phase represents a substance with phase transitions int_energy_mass # By default, all species are consideredįind species/isomers matching a composition specified by comp. Only these species are considered for theĬomputation of the equivalence ratio. Include_species – List of species names (optional). ( basis="mole") or mass fractions ( basis="mass") Oxidizer – Oxidizer species name or mole/mass fractions as a string, array, or dict.īasis – Determines if fuel and oxidizer are given in mole fractions equivalence_ratio ( fuel = 'CH3:0.5, CH3OH.5, N2:0.125', oxidizer = 'O2:0.21, N2:0.79, NO:0.01' ) 0.5 Parameters :įuel – Fuel species name or mole/mass fractions as string, array, or dict. If fuel and oxidizer are not specified, theĮquivalence ratio is computed from the available oxygen and the Other elements are assumed not to participate in oxidation Considers the oxidation of C to CO2, H to H2OĪnd S to SO2. Get the equivalence ratio \(\phi\) of the current mixture, which is aĬonserved quantity. Log_level – Set to a value greater than 0 to write diagnostic output.Įquivalence_ratio ( fuel = None, oxidizer = None, basis = 'mole', include_species = None ) # If -1, the initial mole fraction vector is thrown out, Initial mole fraction vector is used if the element abundances are ThermoPhase object is used as the initial condition. If 0, the initial mole fraction vector in the Outer iterations on T or P when some property pair otherĮstimate_equil – Integer indicating whether the solver should estimate its own Max_iter – For the Gibbs minimization solver, this specifies the number of Max_steps – The maximum number of steps in composition to take to find a converged If it fails the Gibbs solver will be tried. 'auto' - The element potential solver will be tried first, then 'vcs' - the VCS non-ideal equilibrium solver 'gibbs' - a slower but more robust Gibbs minimization solver 'element_potential' - a fast solver using the element potential Get/Set internal energy, specific volume Get/Set internal energy and specific volume Saturation temperature at the current pressure. Get/Set temperature, pressure, and mass fractions. Get/Set temperature, pressure, and mole fractions. Get/Set temperature and density, and mass Get/Set entropy, specific volume [m^3/kg or Get/Set entropy and specific volume [m^3/kg or Get/Set entropy, pressure, and mass fractions. Get/Set entropy, pressure, and mole fractions. Saturation pressure at the current temperature. Get/Set enthalpy, pressure and mass fractions. Get/Set enthalpy, pressure and mole fractions. Get/Set density, pressure, and mass fractions. Get/Set density, pressure, and mole fractions. It is usedĪs a base class for classes Solution and Interface. State of a phase of matter, which might be a gas, liquid, or solid.Ĭlass ThermoPhase is not usually instantiated directly. ThermoPhase ( infile = '', name = '', *, origin = None, yaml = None, thermo = None, species = (), ** kwargs ) #Ĭlass ThermoPhase may be used to represent the intensive thermodynamic These classes are used to describe the thermodynamic state of a system.
