Dacolt has realised various CFD analyses for Duiker, the leading Dutch manufacturer of main burners for sulphur recovery units.
Amongst others, a comparison has been made between two combustion models in ANSYS® FLUENT®:
- Default FLUENT non-premixed equilibrium model
- Dacolt PSR+PDF model
The CFD methodology used is as follows:
- Steady-state, two stream, adiabatic CFD model
- Dacolt PSR+PDF combustion model for chemical kinetics and turbulence / chemistry interaction
- A detailed reaction mechanism (50+ species) is used to generate the look-up table required for Dacolt PSR+PDF, using Tabkin®.
