Detailed Description

2-fluids equation of state base class.

Fluid 1 is supposed to correspond to neutrons, whereas fluid 2 corresponds to e.g. protons. Neutron 4-velocity is $u^\alpha_{\rm n}$ and proton one is $u^\alpha_{\rm p}$

Therefore, the EOS is defined by giving two log-enthalpies AND a relative velocity as inputs. The output are then: two baryonic densities, the total energy density and pressure The enthalpies $f_1$ and $f_2$ are obtained through the formula

\[ {\rm d}{\cal E}=f^1{\rm d}n_1+f^2{\rm d}n_2+\alpha{\rm d}\Delta^2 \label{eeosbfdefent} \]

see Comer, Novak & Prix. Log-enthalpies are then defined as $H_1 = \ln\left( \frac{f^1}{m_1c^2} \right)$, where $m_1$ is the mass of a particle of the first fluid. (same for $H_2$) The relative velocity $\Delta^2$ is defined as in Comer, Novak & Prix. It can be seen as the neutron velocity seen in the frame of protons (or vice-versa): $\Gamma_\Delta = -g_{\alpha\beta} u^\alpha_{\rm n} u^\beta_{\rm p}$ ()

virtual bool Lorene::Eos_bifluid::operator== ( const Eos_bifluid  )  const [pure virtual]

Comparison operator (egality).

Cmp Lorene::Eos_bifluid::press_ent ( const Cmp ent1,
const Cmp ent2,
const Cmp delta2,
int  nzet,
int  l_min = 0 
) const

Computes the pressure from the log-enthalpy fields and the relative velocity.

Parameters:
ent1 [input, unit: $c^2$] log-enthalpy $H_1$
ent2 [input, unit: $c^2$] log-enthalpy $H_2$
delta2 [input, unit: $c^2$] relative velocity $\Delta^2$
nzet number of domains where the pressure is to be computed.
l_min index of the innermost domain is which the pressure is to be computed [default value: 0]; the pressure is computed only in domains whose indices are in [l_min,l_min+nzet-1] . In the other domains, it is set to zero.
Returns:
pressure field [unit: $\rho_{\rm nuc} c^2$], where $\rho_{\rm nuc} := 1.66\ 10^{17} \ {\rm kg/m}^3$

virtual double Lorene::Eos_bifluid::press_nbar_p ( const double  nbar1,
const double  nbar2,

) const [pure virtual]

Computes the pressure from the baryonic densities and the relative velocity.

(virtual function implemented in the derived classes).

Parameters:
nbar1 [input] baryonic density of the first fluid
nbar2 [input] baryonic density of the second fluid [unit: $n_{\rm nuc} := 0.1 \ {\rm fm}^{-3}$]
delta2 [input, unit: $c^2$] relative velocity $\Delta^2$
Returns:
pressure p [unit: $\rho_{\rm nuc} c^2$], where $\rho_{\rm nuc} := 1.66\ 10^{17} \ {\rm kg/m}^3$

Implemented in Lorene::Eos_bf_poly, Lorene::Eos_bf_poly_newt, and Lorene::Eos_bf_tabul.

virtual Eos* Lorene::Eos_bifluid::trans2Eos (  )  const [pure virtual]

Makes a translation from Eos_bifluid to Eos .

(virtual function implemented in the derived classes).

This is only useful for the construction of a Et_rot_bifluid star and ought not to be used in other situations.

Parameters:
relat [input] Relativistic EOS or not.

Implemented in Lorene::Eos_bf_poly, Lorene::Eos_bf_poly_newt, and Lorene::Eos_bf_tabul.
