AFT xStream is a powerful fluid dynamic simulation tool for high-speed, acoustic transients that occur in steam and gas piping systems. 

• 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
