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;
    }
