The specific internal energy is given by

\begin{align} \rho e = (p + a \rho^2) * (1 - b \rho) / (\rho (\gamma -1)) - a \rho^2 \end{align}

Implements ryujin::EquationOfStateLibrary::EquationOfState.

temperature() [1/3]

double ryujin::EquationOfStateLibrary::VanDerWaals::temperature ( double  rho, double  e  ) const

speed_of_sound() [1/3]

double ryujin::EquationOfStateLibrary::VanDerWaals::speed_of_sound ( double  rho, double  e  ) const

inlinefinalvirtual

The speed of sound is given by

\begin{align} c^2 = \frac{\gamma (\gamma -1) (e + a \rho)}{(1 - b\rho)^2} - 2a\rho. \end{align}

Implements ryujin::EquationOfStateLibrary::EquationOfState.

pressure() [2/3]

virtual double ryujin::EquationOfStateLibrary::EquationOfState::pressure ( double  rho, double  e  ) const

virtual

Return the pressure given density rho and specific internal energy e.

Implements ryujin::EquationOfStateLibrary::EquationOfState.

pressure() [3/3]

virtual void ryujin::EquationOfStateLibrary::EquationOfState::pressure ( const dealii::ArrayView< double > &  p, const dealii::ArrayView< double > &  rho, const dealii::ArrayView< double > &  e  ) const

inlinevirtual

Variant of above function operating on a contiguous range of values. The result is stored in the first argument p, overriding previous contents.

Note

The second and third arguments are writable as well. We need to perform some unit transformations for certain tabulated equation of state libraries, such as the sesame database. Rather than creating temporaries we override values in place.
