AFT Impulse

Waterhammer & Surge Analysis Software

AFT Impulse is a powerful fluid dynamic simulation tool used to calculate pressure transients in piping systems caused by waterhammer. Designed for use in liquid systems containing water, petroleum, and refined products, chemical products, cryogens, refrigerants, and more, AFT Impulse is an essential tool with the ability to tackle your most demanding systems…..

Waterhammer & Surge Analysis Software

AFT Impulse is a powerful dynamic simulation and analysis software used to calculate pressure surge transients in liquid piping systems caused by waterhammer.

  • Easily model a wide range of system components and surge devices
  • Understand the transient response of your system, knowing how valves, pumps and other components will dynamically interact with each other.
  • Evaluate the effect of pressure surges due to vapor cavity collapse by modeling vapor cavitation and liquid column separation.
  • Validate the design of safety features to produce safer, more economical pipe systems.
