Detailed Description

template<class Specie>
class Foam::Boussinesq< Specie >

Incompressible gas equation of state using the Boussinesq approximation for the density as a function of temperature only:

    rho = rho0*(1 - beta*(T - T0))

Coefficient mixing is very inaccurate and not supported, so this equation of state is not applicable to mixtures.

Usage
Property Description
rho0 Reference density
T0 Reference temperature
beta Coefficient of thermal expansion

Example specification of the Boussinesq equation of state:

    equationOfState
    {
        rho0            1;
        T0              300;
        beta            3e-03;
    }
