TableBase, TableFile and Table now combined into a single simpler Table class which handle both the reading of embedded and file data using the generalised TableReader. The new EmbeddedTableReader handles the embedded data reading providing the functionality of the original Table class within the same structure that can read the data from separate files. The input format defaults to 'embedded' unless the 'file' entry is present and the Table class is added to the run-time selection table under the name 'table' and 'tableFile' which provides complete backward comparability. However it is advisable to migrate cases to use the new 'table' entry and all tutorial cases have been updated.

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.
