Description

Incompressible Pipe Flow Analysis & System Modeling Software

Applied Flow Technology (AFT) Fathom is practical fluid dynamic simulation software used to calculate pressure drop and flow distribution in liquid and low velocity gas piping and ducting systems.

Designed for fluid systems containing:

  • Water
  • Petroleum and refined products
  • Chemical products
  • Cryogens
  • Refrigerants
  • Low velocity gases
  • And more

AFT Fathom is particularly useful for:

  • Pipe Sizing
  • Pump sizing and Selection
  • Control Valve sizing and Selection
  • Simulating System operation and component interaction
  • Evaluating 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 Fathom…

  • Accurately simulates individual system components and their interaction
  • 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

Features
