    AFT Arrow


    Compressible Pipe Flow Analysis & System Modeling Software

    AFT Arrow is a fluid dynamic simulation tool 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 many more

    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

    Evaluate New Designs and Improve Your Installed Systems

    AFT Arrow…

    • Accurately simulates individual system components and their interaction including effects of heat transfer, real gases and choked flow
    • Tightly integrates equipment characteristics, analysis and output with your system’s schematic representation
    • Provides a wide array of features without sacrificing your need for a short learning curve
    • Frees you to focus on your system, not the mechanics of software manipulation
    • Significantly improves the quality of systems engineering you can achieve, leading to less costly, more efficient and more reliable piping systems


    • 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 with data linkage
    • 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

    AFT Arrow Add-on Module

    Extend AFT Arrow’s modeling capabilities with the  Goal Seek and Control module (GSC). GSC automates determination of input to achieve specified output & simulate control functions. The module can work within AFT Arrow and with your existing AFT Arrow models.
