AFT xStream Overview

This potent fluid dynamic simulation tool for high-speed acoustic transients in steam and gas piping systems. You can accurately simulate how your steam and gas systems respond to potentially harmful transient events. You can easily change system input data, including short valve positions, compressor operation, control setpoints, pressures, temperatures, etc.

Features of AFT xStream

Built-in steady-state solver to automatically initialize the 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
2D flow diagram or isometric view interface
Built-in libraries of fluids and fittings which can be extended and customized
Chempak add-on utility provides a thermophysical database of almost 600 gases.
