Impulse: Design and Operate Your System with Greater Safety and Reliability

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.

 Capabilities

  • Model a wide range of system components and surge supressing devices for both design and operational cases
  • Initiate transients based on time or events in the system
  • Reduce surge magnitudes by slowing system component changes such as valve closures or pump speed
  • 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
  • Experiment with operating conditions and scenarios
  • Quickly and easily change system input data, including valve positions, pump operation, control set points, pressures, temperatures and more

 Benefits

  • 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
  • Avoid lost revenue resulting from incidents that cause down time
  • Validate the design of safety features
  • Understand the transient response of your system
  • Know the dynamic interaction of valves, pumps and other components

 

 Typical Applications

  • Ensuring that pressure extremes are within design allowables
  • Sizing and locating surge suppression equipment
  • Determining imbalanced pipe forces for sizing structural supports
  • Troubleshooting existing systems to determine the cause of operational problems
  • Evaluating the effect of pressure surges due to vapor cavity collapse
