!The fluid files contain general information about the fluid in the first 15 to 20 lines, followed by sections for the
|
|
! equations of state, transport equations, and auxiliary equations. Equations of state are listed first. The NIST recommended
|
|
! equations begin with a hash mark (#). The secondary equations begin with the @ symbol. These symbols can be swapped to
|
|
! select a secondary equation as primary and the primary as secondary. The equation of state section also contains auxiliary
|
|
! equations for the ideal gas heat capacity or ideal gas Helmholtz energy. Below the equations of state (both primary and
|
|
! secondary) are the transport equations, first viscosity and then thermal conductivity. These are then followed by the
|
|
! secondary equations if available. The transport section also contains auxiliary equations required to calculate either the
|
|
! dilute gas state or the critical enhancement. At the end of the file are additional but not necessary auxiliary equations,
|
|
! including simple equations for the vapor pressure, saturated liquid and vapor densities, melting line (for some fluids), and
|
|
! sublimation line (for even fewer fluids). This section also contains the equations for dielectric constant and surface
|
|
! tension if available. The sections are divided by different symbols (these being _-+=^*~) to aid the eye in locating a
|
|
! particular section. Secondary equations are indented 10 spaces to avoid confusion with the NIST recommended equations. The
|
|
! end of the fluid file is marked with @END. Anything below that is ignored.
