AFT Impulse™
      offers the ease-of-use of a drag-and-drop interface and built-in
      waterhammer modeling expertise. AFT Impulse helps you design
      and operate your systems with greater reliability and safety
      by avoiding the potentially catastrophic effects of waterhammer
      and other undesirable system transients. 



      Piping systems engineers typically do not have the time to become
      specialists in waterhammer modeling. Now they don’t have
      to. Now they can be equipped with the proper tools to design
      and analyze for waterhammer transients in liquid systems containing
      water, petroleum and chemical products, cryogens, refrigerants
      and more. Waterhammer specialists will find a no compromise tool
      capable of modeling a broad range of waterhammer events, including
      transient cavitation and various surge suppression devices. AFT
      Impulse provides a built-in library of fluids and fittings, variable
      model configurations, pump and control valve modeling and much
      more. Scenario Manager raises the what-if potential of waterhammer
      modeling to a new level. Multiple system configurations varying
      by any modeling parameter are easily managed within a single
      model file with a familiar hierarchical interface. Changes in
      the base model are automatically inherited by alternate design
      cases.


      
AFT Impulse incorporates
      a steady-state solver providing seamless transfer of initial
      conditions to the transient analysis. The traditional Method
      of Characteristics are employed to solve the transient mass and
      momentum equations of pipe flow. Modeling vapor cavitation and
      liquid column separation, the effect of pressure surges due to
      vapor cavity collapse may be evaluated. Modeling tools for a
      wide range of system components and surge devices are included.
      Transients can be initiated based on time or on events in the
      system. For example, a valve closure transient may be initiated
      when a specified pressure level is attained at a location. From
      the powerful drag-and-drop model building features to the fully
      customizable output, AFT Impulse is a powerful tool ready to
      tackle your most demanding design problems.
