Modeling Features

Pipes

  • Specify diameter, length and roughness or select by material type and schedule from the built-in database
  • Select friction modeling from an extensive list including:
    • pipe roughness
    • Panhandle method
    • Weymouth method
  • Model heat transfer and add insulation layers – predict insulation surface temperatures to ensure compliance with workplace safety regulations
  • Use embedded fittings to reduce workspace complexity

Compressors & Fans

  • Explore the interaction of your system with compressors and fans
  • Model compressor and fan power and associated energy costs
  • Select between fixed specified flow or modeling with a compressor or fan curve
  • Model VFDs and pump control to maintain a set flow rate or head/pressure

Valves

  • Model relief valves and check valves
  • Determine control valve capacity and insure adequate pressure drop
  • Simulate pressure and flow control valves to test system interaction in the design stage
  • Display effective Cv and K factor values for all valves in the system
  • Identify control valve position to ensure stable valve operation

Fluid Property Models

  • Built in ASME steam tables
  • Optional chempak add-on with 600 gases
  • Configurable interpolation models for equation of state and enthalpy
  • Redlich-Kwong
  • Three parameter method

Scenario Manager

  • Evaluate “What-if” cases by comparing several scenarios
  • Make data changes in one scenario which can be passed down to dependent scenarios
  • Easily develop and switch between different operating conditions or configurations
  • Evaluate new or expanding system configurations

Reporting Features

Output

  • Display pipe and junction reporting sections all at once or individually
  • Select output format, units and displayed items through Output Control
  • Make changes to the format without re-running the analysis
  • Export results to a file or copy/paste into Excel for additional reporting options
  • View input and output data for multiple scenarios simultaneously

Visual Results

  • Displays selected input or output parameters with your model schematic
  • Vary pipe color in the model according to parameters you define based on pressure, temperature, flow and many others to see results in the context of your system
  • Clearly illustrate individual lines in the context of your entire system using color mapping

Graph Results

  • Graphs of flow, pressure, temperature and many other parameters are quickly and easily generated by pipe or along a flowstream
  • Show compressor or fan vs. system curves

How does it work?

AFT Arrow’s powerful solution engine simultaneously solves five fundamental equations; mass, momentum, energy, state and Mach number. AFT Arrow uses a modified Newton-Raphson matrix iteration method plus proprietary methods developed by AFT so you can achieve a true and rigorous compressible flow solution.
