The software has the capability of analyzing a number of pre-defined (e.g. Helium, Methane, Chorine, Water, Ethanol, ) or user defined (e.g. Steam [Steam will become a defined medium in EFD.Lab 6]) fluids in various flow regimes. A number of Solids are also included for Heat Transfer analysis. Click the link below to view a list of the materials and surfaces that may be used:


The following non-newtonian models are available:
  • Herschel-Bulkley
  • Carreau
  • Power law
  • Viscosity Constant


Although fluid flow is 3 dimensional in nature, it is often desirable to analyze a problem in two-dimensions. EFD.Lab can perform these analyses. Examples include an aerofoil with wing tip effects (3D) or a simple cross-section (2D).


Examples of external flow include the wind patterns around buildings, boat sails and golf balls in flight. Examples of internal flow include flow through valves, dampers, pipelines, HVAC systems, cabin ventilation and electronic system cooling.


With this feature, the software can predict erosion rates due to particles (dust or droplets of various materials) being carried in the fluid stream.


Gravity may be imposed on the system to calculate buoyancy effects. The direction of the gravity may be applied in any direction but not towards the origin so the convection zone in stars cannot be modeled at this point. Examples include the analysis of computer equipment in a closed 19 inch rack.
