Class
Foam::saturationModels::function1
Description
Saturation vapour temperature in terms of
the vapour pressure (in Pa). The saturation temperature in Kelvins is
specified as a Foam::Function1 type, to enable use of, e.g. constant,
polynomial, table values.
Currently this class only provides \f$T_sat\f$, the inverse function to
return the vapour pressure for a given temperature are not implemented.
Examples:
\verbatim
type function1;
function polynomial
(
(308.0422 0)
(0.0015096 1)
(-1.61589e-8 2)
(1.114106e-13 3)
(-4.52216e-19 4)
(1.05192e-24 5)
(-1.2953e-30 6)
(6.5365e-37 7)
)
\endverbatim
\verbatim
type function1;
function csvFile;
functionCoeffs
{
nHeaderLine 1;
refColumn 0;
componentColumns (1);
separator ",";
mergeSeparators no;
file "filename.csv";
outOfBounds clamp;
interpolationScheme linear;
};
