Description

template<int id, class Scalar>
class Dumux::Components::Constant< id, Scalar >

Template Parameters

id	The id used to read from the input file / parametertree
Scalar	The type used for scalar values

Note

For the constant component with id=1 you would specify the parameters in the input file as follows

[1.Component]
MolarMass = 0.018 # kg/mol

If you only have one component you can also omit the "1.".

gasInternalEnergy()

template<int id, class Scalar >

static Scalar Dumux::Components::Constant< id, Scalar >::gasInternalEnergy ( Scalar  temperature, Scalar  pressure  )

inlinestatic

   Definition of enthalpy: \f$h= u + pv = u + p / \rho\f$.

   Rearranging for internal energy yields: \f$u = h - pv\f$.

   Exploiting the Ideal Gas assumption (\f$pv = R_{\textnormal{specific}} T\f$)gives: \f$u = h - R / M T \f$.

   The universal gas constant can only be used in the case of molar formulations.

Parameters

temperature	temperature of phase in $[\mathrm{K}]$
