Steam & Gas Transient Analysis Software
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 disruptive transient events.
Simulate and Solve Your Challenging Steam and Gas Transient Problems
How does it work?
AFT xStream™ incorporates a steady-state solver providing seamless transfer of initial conditions to the transient analysis. Steady-state solutions are determined using a modified Newton-Raphson matrix iteration. The traditional Method of Characteristics is used to solve the transient mass and momentum equations of pipe flow.
An AFT xStream Add-on Module
This module helps engineers identify and avoid resonant frequencies in systems, especially in those caused by reciprocating compressors. Problems can arise when the frequencies that are excited by pulsation are at or near the acoustic resonant frequencies of a fluid system. The module is used to calculate the acoustic resonance frequencies that could damage system equipment.
