Function Documentation

◆ sound_speed_squared() [1/2]

template<typename DataType , size_t ThermodynamicDim>

Scalar< DataType > hydro::sound_speed_squared	(	const Scalar< DataType > &	rest_mass_density,
		const Scalar< DataType > &	specific_internal_energy,
		const Scalar< DataType > &	specific_enthalpy,
		const EquationsOfState::EquationOfState< true, ThermodynamicDim > &	equation_of_state
	)

noexcept

Computes the relativistic sound speed squared.

The relativistic sound speed squared is given by \(c_s^2 = \left(\chi + p\kappa / \rho^2\right)/h\), where \(p\) is the fluid pressure, \(\rho\) is the rest mass density, \(h = 1 + \epsilon + p / \rho\) is the specific enthalpy \(\chi = (\partial p/\partial\rho)_\epsilon\) and \(\kappa = (\partial p/ \partial \epsilon)_\rho\), where \(\epsilon\) is the specific internal energy.
