AFT Impulse for Windows models waterhammer/surge transients in complex pipe networks using an innovative drag and drop modelling interface. AFT Impulse will help you to predict accurately the effect of water flow in a pipe network, thus preventing disaster that may arise due to the effect of water hammer.

 

Features of AFT Impulse

  • Drag and drop modelling from an onscreen palette of components
  • Open and closed (i.e. re-circulating) systems
  • Network systems that branch or loop with no limit on number of loops
  • Systems with pump, control and relief valves transients
  • Systems with transient vapour cavitation and column separation
  • Systems with surge tanks, gas accumulators and/or liquid accumulators
  • AFT Impulse can model a large range of liquid systems including Water, Cryogens, Petroleum, Liquid Hydrocarbons, Chemical Products, Refrigerants
  • AFT Impulse's powerful solution engine is based on the Method of Characteristics solution of the mass and momentum equations. This technique accounts for liquid sonic speed and pipe elasticity
  • AFT Impulse uses simple drag and drop operations to build a waterhammer model of a generalised pipe system. A checklist guides you through the model building process step by step. Steady and transient pipe system data is entered for components through Specifications windows, which are opened by double clicking the component of interest. Additional global editing features simplify making large scale changes to the model
  • AFT Impulse generates numerous output reports and graph types, all of which are customisable. All printed output is of report quality. An innovative Visual Results window shows the transient solution in motion colour
  • Animated colour replay of transient solutions

 

AFT Impulse System Requirements

  • Windows 95 and higher or NT 4.0 and higher
  • 64MB RAM
  • 25MB hard disk space
  • Network or stand alone
