AFT Impulse

Waterhammer & Surge Analysis Software

AFT Impulse is a 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 particularly useful for:

  • Ensuring that pressure extremes are within design allowables.
  • Sizing and locating surge suppression equipment.
  • Determining imbalanced pipe forces and sizing structural supports.
  • Troubleshooting existing systems to determine the cause of operational problems.

Design and Operate Your System with Greater Safety and Reliability

AFT Impulse will help…

  • Avoid potentially catastrophic effects of waterhammer and other undesirable system transients.
  • Alleviate possible financial and environmental issues associated with inadequate system designs or operational procedures.
  • Prevent events that have serious consequences to life and property.
  • Avoid lost revenue resulting from incidents that cause down time.
  • Validate the design of safety features.

Features

  • Advanced transient solver based on Method of Characteristics
  • Built-in steady-state solver to automatically initialize waterhammer transient
  • Detailed pump inertial modeling for trips and startups including state-of-the-art, four quadrant methods
  • Models transient cavitation and liquid column separation
  • Intuitive drag and drop interface
  • Scenario Manager to track all design variants and operational possibilities in a single model file with data linkage
  • Integrated graphing and reporting
  • Animation features to dynamically graph transients
  • Generates force imbalance files that can be automatically read into CAESAR II ® and TRIFLEX ® pipe stress dynamic models
  • Built-in intelligence to guide you in building better models

World Class Support

AFT Impulse is backed by a technical support team of engineers. More than software support, Applied Flow Technology provides the waterhammer analysis knowledge that comes with extensive real world experience.
