Fluid mechanics
•Aspen HYSYS® Pipe Segment
-incompressible flow assumed
-single-phase vapor flow
-ignores the kinetic energy term of the energy balance equation for all phases.
•Aspen HYSYS® Compressible Gas Pipe
-single-phase vapor flow only
-solves the mass, momentum and energy balance equations simultaneously
-intended for dynamic modeling.
4. Fluid mechanics. Modeling
•Aspen HYSYS® Hydraulics (AHH)
-solves the mass, momentum and energy balance equations simultaneously on each phase present.
-provides rigorous two-phase flow models with slip included.
-equation-oriented solution for the entire flowsheet (so it handles networked piping)
