Chempak Property Database

Comprehensive thermo-physical properties on a wide range of fluids for AFT’s family of pipe flow modeling software products.

  • For incompressible pipe flow analysis
    • data on ~700 fluids for AFT Fathom and AFT Impulse
    • assemble non-reacting static mixtures
  • For compressible flow analysis
    • data on ~600 gases for AFT Arrow
    • model both static mixtures and dynamic mixing resulting from intersecting flow streams
  • Fluids listed by up to 3 commonly used names
  • Fluids listed by formula and chemical structure
  • Sort on any of the identifiers

Chempak Viewer

The viewer to access the Chempak Property Database as a stand-alone application are now for free in all AFT software.

  • Assemble non-reacting mixtures on a mass or mole basis.
  • Calculate fluid or mixture properties for any combination of the available input parameters as a single point, two point or a range of inputs.
  • Save or set your parameter and unit preferences as the default.
  • Save and reload input sets.
  • Save fluid and mixture sets for quick recall using the Recent Fluids list.
  • Specify a name for any fluid or mixture and it appears along with the standard Chempak name.
  • Change units ‘on the fly’ by double-clicking an output column header.
