    AFT Impulse – Waterhammer & Surge Analysis Software  


    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 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
    • Evaluating the effect of pressure surges due to vapor cavity collapse

    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


    • 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 start-ups including state-of-the-art, four quadrant methods
    • Built-in library of fluids and fittings
    • Models liquid column separation caused by transient cavitation
    • Extensive cavitation modeling
    • Scenario Manager to track all design variants and operational possibilities in a single model file with data linkage
    • Comprehensive relief valve modeling
    • Integrated graphing and reporting
    • Animation features to dynamically graph transients
    • Create video files from animations to share your results
    • 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
