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
  • Hazen Williams
  • MIT Equation for crude oil
  • Miller Turbulent Method for light hydrocarbons
  • User specified pipe resistance
  • Friction modeling includes pulp & paper and non- Newtonian fluids
• 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

Pumps

• Explore the interaction of pumps and your system
• Model pump power and associated energy costs
• Evaluate a large range of potential pump selections by importing external databases or linking to Intelliquip™ powered pump selectors
• Select between fixed specified flow or modeling with a pump curve
• Model VFDs and pump control to maintain a set flow rate or head/pressure
• Automatically correct for viscous fluid behavior
• Predict available NPSH

Valves

• Model relief valves, check valves, three-way 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

• Constant fluid properties
• Variable fluid properties - you can specify differing fluid properties on a pipe by pipe basis
• Heat transfer with energy balance, single fluid - modeling heat transfer through pipe boundaries and heat exchangers along with fluid property variations with temperature
• Heat transfer with energy balance, multiple fluids - modeling heat transfer between multiple hydraulic circuits thermally linked through heat exchangers

Scenario Manager

•  Evaluate “What-if” cases by comparing several scenarios
• Make data changes in one scenario 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
• Display differing units for parameters simultaneously
• 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 system curves and pump vs. system curves
• Demonstrate how system performance varies based on the number of pumps in operation by showing different pump curve combinations in one pump vs. system curve graph
• Display multiple graphs concurrently

Viewer

Share your models with anyone who may not need a full version of AFT Fathom. The Viewer is a free application that lets you:

• Open a model and view any of the windows (Workspace, Model Data, Output, Visual Report, Graph Results)
• Run the model and graph output data
• Print and export data
• You cannot edit an existing model or create new models with the Viewer.
