AFT Impulse 7

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.

Design and Operate Your System with Greater Safety and Reliability

  • Avoid potentially catastrophic effects of waterhammer and other undesirable system transients
  • Initiate transients based on time or events in the system
  • Reduce surge magnitudes by slowing system changes such as valve closures or pump speed
  • Minimize the adverse effects of surge by changing piping or equipment to reduce velocities
  • Calculate transient unbalanced forces and define forces sets as location pairs or single points
  • Specify alerts that automatically highlight output values that are out of range for flow, pressure or velocity
  • Compile libraries of your frequently used piping components and quickly select them from a drop down list
  • Customize and configure your workspace
Typical Applications
  • Ensure pressure extremes are within design allowables
  • Waterhammer calculation
  • Size and locate surge suppression equipment
  • Determine imbalanced pipe forces and sizing structural supports
  • Troubleshoot existing systems to determine the cause of operational problems
  • Evaluate the effect of pressure surges due to vapor cavity collapse
AFT Impulse Add-On Modules
With these software extension tools, you can quickly and efficiently
complete projects. Modules can work individually or together within
AFT Impulse and with your existing AFT Impulse models.

Settling Slurry

The only commercial software solution that can model both non-settling and settling slurry waterhammer effects.

Pulsation Frequency Analysis

Helps identify and avoid resonant frequencies in systems, especially in those caused by positive displacement pumps.
