Description

template<int id, class Scalar>
class Dumux::Components::Constant< id, Scalar >
Template Parameters
idThe id used to read from the input file / parametertree
ScalarThe 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.
