Class
Foam::saturationModels::polynomial
Description
Polynomial equation for the saturation vapour temperature in terms of
the vapour pressure (in Pa).
\f[
T_sat = \sum_i C_i p^i
\f]
where \f$p\f$ is the pressure in Pa and \f$C\f$ are the coefficients.
Currently this class only provides \f$T_sat\f$, the inverse function to
return the vapour pressure for a given temperature are not implemented.
