Yes, AFT Impulse uses the Discrete Vapor Cavity Model or Discrete Gas Cavity Model.

No, AFT Impulse only models transients in liquid systems.

Yes. Pumps can be modeled as a prescribed speed transient or the speed can be calculated based on pump inertial characteristics.

Yes, positive displacement pumps can be modeled as steady operation with periodic flow or during startups and shutdowns.

Yes, see the Air Valve junction topic.

Yes, see the Control Valve junction topic.

Yes, users can assign an elevation profiles to individual pipes.

Yes, AFT Impulse allows you to include these as "design alerts". Design alerts can be cross-plotted against pressure profiles.

AFT Impulse offers a standard set of properties for common fluids in the AFT Standard Fluids library. It also offers the NIST REFPROP library included with all AFT applications. Users can also utilize the optional Chempak data add-on which is a chemical property library of up to 700 fluids with mixing capability. Use the library as a stand-alone application with the Chempak Viewer or access the library from within Microsoft Excel with the Chempak Add-in.

Yes, AFT Impulse offers Power Law and Bingham Plastic non-newtonian fluid models, and offers the Duffy method and Brecht & Heller for pulp and paper system modeling.

Impulse can model partially filled pipes at the end of a flow path or run. This capability is primarily intended to handle the situation where a supply riser to a cooling tower or condenser, for example, partially drains when the system is not in operation.
