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.
