Combustion and reacting flow
Combustion and reacting flow in OpenFOAM, from a workbench
Premixed and non-premixed combustion, spray and reacting flow with reactingFoam, XiFoam and sprayFoam — chemistry, thermophysical properties and the fields they need, set up for you.
What it is
Chemical reaction coupled to the flow and to the energy equation. Premixed cases track flame-front propagation; non-premixed cases resolve mixing and reaction together; spray adds a liquid phase that evaporates before it burns.
What the application sets up
- Thermophysical and chemistry configuration for the selected mechanism
- The species and energy fields a reacting solve requires
- Ignition setup for premixed cases
- Lagrangian injection parameters for spray
Typical uses
- Burner and furnace design
- Gas turbine combustor screening
- Engine spray and ignition studies
- Flare and vent dispersion with reaction

In every tier
This analysis type is in the free build. The free tier limits mesh size to 250,000 cells and solving to one core — not which physics you may use.
On accuracy, plainly.
