AFT xStream is a powerful fluid dynamic simulation tool for high-speed, acoustic transients that occur in steam and gas piping systems. Uncertainty in design and operations costs money and time. Now you can accurately simulate how your steam and gas systems will respond to potentially harmful transient events.


Primary Features of AFT xStream:

  • Built-in steady-state solver to automatically initialize system before the transient
  • Automatic pipe sectioning based on steady-state acoustic velocities
  • Compound transient event logic to model complex control sequences
  • Scenario Manager to track all design variants and operational possibilities in a single model file
  • Integrated graphing and reporting
  • Animation tools for visual interpretation of complex transient interactions
  • Generates force imbalance files that can be automatically read into CAESAR II, ROHR2, AutoPIPE and TRIFLEX pipe stress dynamic models
  • 2D flow diagram or isometric view interface
  • Built-in libraries of fluids (including NIST REFPROP and ASME Steam Tables) and fittings which can be extended and customized
  • Chempak add-on utility provides a thermophysical database of almost 600 gases - allows you to define non-reacting pre-mixtures and simulate dynamic flow mixing


Changes to computation logic that could impact results
- Difference Exit forces incorrectly accounted for ambient pressure on the nozzle area. This has been corrected to only include the momentum force. The ambient pressure force is balanced on the other side of the difference pair.
- Fixed elevation changes along pipes not being accounted for correctly. The sign of the elevation change was not correct, so elevation increases would mistakenly show an increase in energy down the pipe.
Changes that do not impact results
- Fixed an issue where the Graph Parameters Form was not reinitializing properly when changes are made to the model.
- Fixed some PDF/RTF export issues for Print Preview.
- Fixed an issue where the format menu for Graph titles was showing scaling values. Setting the values would cause an error.
- Fixed an issue where custom plot names are not showing for stacked graphs.
- Added function for Materials linking with Import Piping Layout.
- Fixed an issue where the 'Special Condition' menu item was not functioning properly.
- Fixed an issue where renaming a scenario below the current scenario on the scenario tree would deactivate the current scenario.
- Fixed an issue where the Graph format menu would appear on the wrong screen.
- Fixed a color map refresh issue for Visual Report.
- Fixed the crosshair label for graphs to show the correct parameter
- Fixed an issue that prevented the Overview Map from opening.
- Output will no longer clear when OK is clicked in Analysis Setup when no changes were made.

  • Accurately simulate high-speed transients in steam and gas piping systems including choked flow conditions
  • Evaluate overall system response and transient pipe forces after steam and gas turbine trips
  • Predict transient supply pressures, temperatures and flows to operating gas compressors and turbines when one trips offline
  • Simulate tank blowdowns and charging, and how long it takes to reach desired pressures
  • Predict transient pressures and flows due to heat exchanger tube ruptures
  • Easily change system input data including transient valve positions, compressor operation, control set points, pressures, temperatures and more
  • Initiate transients based on time or events in the system
Typical Applications

  • Ensure pressure, temperature and flow extremes are within design allowables
  • Determine imbalanced pipe forces for sizing structural supports
  • Troubleshoot existing systems to determine the cause of operational problems
