Applied Flow Technology Arrow

Applied Flow Technology (AFT)  Arrow is practical fluid dynamic simulation software used to calculate pressure drop and flow distribution in gas piping and ducting systems. Designed for compressible flow systems containing steam, compressed air, chemical and petrochemical process gases, natural gas transport and more, AFT Arrow is an indispensable tool to help you tackle your most challenging systems.

AFT Arrow is particularly useful for:

  • 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


  • Advanced marching methods provide highly accurate results
  • Detailed modeling for fans and compressors, control valves, heat exchangers and other components
  • Conduct compressor and fan energy cost analysis
  • Conduct thermal analysis including piping heat transfer and heat exchanger modeling
  • Scenario Manager tracks all design variants and operational possibilities in a single model file
  • Integrated graphing and reporting
  • Built-in library of gases and fittings can be extended and customized
  • Built-in ASME steam properties
  • Optional Chempak add-on utility provides a thermophysical database of almost 600 gases – allows you to define non-reacting pre-mixtures and simulate dynamic flow mixing


  • Understand the fluid dynamic and thermodynamic behavior of your system
  • Predict how pipes, valves, compressors, fans and other components will interact with each other
  • Evaluate the performance of new designs
  • Assure all design requirements are met
  • Identify and correct operational problems
  • Produce less costly, more efficient and more reliable piping systems
