/*
in order to use the Boussinesq approximation for the density is sufficient to use the icoPolynominial model by setting its coefficients in the following way
[>> BOUSSINESQ TO icoPolynomial converter]

Rearranging Boussinesq equation in the form of rho = A + B * T
rho = rho_0 - rho_0 * Beta * (T  - T_0)
rho = rho_0 + rho_0 * Beta * T_0 - rho_0 * Beta * T

By using the following values :
        rho_0  = 1;
        T_0  = 298;
        Beta = 0.0034; // thermal expansion coefficient of air : At normal standard conditions of 25 degree Celsius or 298 Kelvin, Thermal expansion coefficient of air is said to be around 0.0034/K.

A = rho_0 + rho_0 * Beta * T_0 = 1+1*0.0034*298 = 2.0132
B = -rho_0 * Beta = -0.0034

Therefore in the icoPolynomial subdictionaries in constant/thermo.incompressiblePoly we will set :

    equationOfState
    {
        rhoCoeffs<8>   ( 2.0132 -0.0034 0 0 0 0 0 0 ); // rho = A + B * T
    }
