AFT Arrow 8

Compressible Flow Simulation Tool

AFT Arrow is a fluid dynamic simulation tool used to calculate pressure drop and flow distribution in gas piping and ducting systems.

  • Accurately simulate individual components and their interaction including effects of heat transfer, real gases and choked flow
  • Tightly integrate equipment characteristics, analysis and output with your system’s schematic representation
  • Utilize a wide array of features without sacrificing your need for a short learning curve
  • Compare the performance of new designs and assure all design requirements are met.
  • Identify and correct operational problems in installed systems
  • Significantly improve the quality of systems engineering and produces less costly, more efficient and more reliable piping systems
Capabilities
  • Experiment with operating conditions and scenarios
  • Easily change system input data, including valve positions, pump operation, control set points, pressures, temperatures and more
  • Model a wide range of system components for both design and operational cases
  • Simulate ideal or real gases
  • Choose between isothermal, adiabatic or generalized heat transfer conditions
  • Vary your system lineup: open and close pipes and valves, turn compressors or fans on or off, set control valves to fail position
  • Conduct flow analysis with high velocities including sonic choking
  • Compile database libraries of your frequently used components and quickly select them from a drop down list
  • Assemble non-reacting mixtures and analyze dynamic mixing resulting from intersecting flow streams
  • Model and analyze rotating piping systems such as those found in steam and gas turbines
  • Model effects of elevation changes such as in tall structures, subsurface mines and overland pipelines
  • Evaluate codes and industry standards applied in the model
  • Import piping layouts from:
  • Import and export files in EPANET format
  • Clearly import Excel data into multiple scenarios and export with the Excel Export Manager
Typical Applications
  • Pipe and Duct Sizing
  • Relief valve sizing and system calculations
  • Compressor and Fan sizing and Selection
  • Control Valve sizing and Selection
  • Simulating System operation and component interaction
  • Choked Flow calculations
  • Evaluating pipe insulation and heat transfer in pipes and heat exchangers
  • Troubleshooting existing systems to determine the cause of operational problems
