Detailed Description

Base class for a phase with plasma properties.

This class manages the plasma properties such as electron energy distribution function (EEDF). There are two ways to define the electron distribution and electron temperature. The first method uses setElectronTemperature() to set the electron temperature which is used to calculate the electron energy distribution with isotropic-velocity model. The generalized electron energy distribution for isotropic-velocity distribution can be expressed as [1,2],

\[ f(\epsilon) = c_1 \frac{\sqrt{\epsilon}}{\epsilon_m^{3/2}} \exp(-c_2 (\frac{\epsilon}{\epsilon_m})^x), \]

where \( x = 1 \) and \( x = 2 \) correspond to the Maxwellian and Druyvesteyn (default) electron energy distribution, respectively. \( \epsilon_m = 3/2 T_e \) [eV] (mean electron energy). The second method uses setDiscretizedElectronEnergyDist() to manually set electron energy distribution and calculate electron temperature from mean electron energy, which is calculated as [3],

\[ \epsilon_m = \int_0^{\infty} \epsilon^{3/2} f(\epsilon) d\epsilon, \]

which can be calculated using trapezoidal rule,

\[ \epsilon_m = \sum_i (\epsilon^{5/2}_{i+1} - \epsilon^{5/2}_i) (f(\epsilon_{i+1}) + f(\epsilon_i)) / 2, \]

where \( i \) is the index of energy levels.

For references, see Gudmundsson [9]; Khalilpour and Foroutan [17]; Hagelaar and Pitchford [10], and BOLOS [23].

Constructor & Destructor Documentation

◆ PlasmaPhase()

PlasmaPhase ( const string &  inputFile = "",
const string &  id = "" 
)
explicit

Construct and initialize a PlasmaPhase object directly from an input file.

The constructor initializes the electron energy distribution to be Druyvesteyn distribution (m_x = 2.0). The initial electron energy grid is set to a linear space which starts at 0.01 eV and ends at 1 eV with 1000 points.

Parameters
inputFileName of the input file containing the phase definition to set up the object. If blank, an empty phase will be created.
idID of the phase in the input file. Defaults to the empty string.

Definition at line 14 of file PlasmaPhase.cpp.

Member Function Documentation

◆ type()

string type ( ) const
inlineoverridevirtual

String indicating the thermodynamic model implemented.

Usually corresponds to the name of the derived class, less any suffixes such as "Phase", TP", "VPSS", etc.

Since
Starting in Cantera 3.0, the name returned by this method corresponds to the canonical name used in the YAML input format.

Reimplemented from IdealGasPhase.

Definition at line 74 of file PlasmaPhase.h.

◆ initThermo()

void initThermo ( )
overridevirtual

Initialize the ThermoPhase object after all species have been set up.

This method is provided to allow subclasses to perform any initialization required after all species have been added. For example, it might be used to resize internal work arrays that must have an entry for each species. The base class implementation does nothing, and subclasses that do not require initialization do not need to overload this method. Derived classes which do override this function should call their parent class's implementation of this function as their last action.

When importing from an AnyMap phase description (or from a YAML file), setupPhase() adds all the species, stores the input data in m_input, and then calls this method to set model parameters from the data stored in m_input.

Reimplemented from ThermoPhase.
