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 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

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
