Walk-Through Examples (English Units)

The AFT xStream Walk-Through Examples are designed to get new users trained to use AFT xStream correctly in the shortest amount of time. If you are using AFT xStream for the first time, start with the Beginner - Tank Blowdown example because it offers an in-depth explanation of how to use AFT xStream. Otherwise, choose an example from the table below that you wish to learn more about.

Completed versions of the example model files are included with the default installation: C:\AFT Products\AFT xStream 3\Examples

Note: The examples are available in both English and Metric units. To work these examples in a different unit system, open the appropriate example, and click the link to the alternate unit system example found at the top of each example.

Example	Fluid	Pipes	Description
Beginner - Tank Blowdown	Nitrogen	2	An in depth discussion of model building in AFT xStream and a basic overview of the software interface and Primary Windows. Models a simple valve opening during a tank blowdown.
Gas Turbine Fuel System	Methane	11	A compressor is passing natural gas through a heat exchanger before being used in the combustion baskets of a turbine system. This example evaluates the effect the sudden closure of one of the 3 control valves has on the temperature of the system. The effect of the Minimum Number of Sections per Pipe parameter is also shown.
Fluid Library Comparison - Steam Turbine Shutdown	Steam	12	Two turbines in a high pressure steam system are simultaneously shut off as a bypass line valve is opened. This model demonstrates factors to know to evaluate which fluid library to use in your system, as well as demonstrating how to construct a model in the isometric drawing mode.
Pipe Forces from Turbine Shutdown	Steam	14	Two turbines in a high pressure steam system are simultaneously shut off. This model demonstrates the transient forces of the steam within the system as well as the effect that the transient duration has on these forces. Finally, this example shows how to export the force file once the forces are obtained.
PFA Add-on Module - Frequency Analysis	Methane	5	A frequency analysis is performed on a system with a positive displacement compressor to determine the acoustical frequencies for the existing piping configuration using the Pulsation Frequency Analysis (PFA) Module.
