Syngas Combustion in a Round-Jet Burner

Application ID: 14881

The model simulates non-premixed turbulent combustion of syngas (synthesis gas) in a simple round-jet burner.

Syngas is a gas mixture, primarily composed of hydrogen, carbon monoxide and carbon dioxide. The name syngas relates to its use in creating synthetic natural gas. In the model, syngas is fed from a pipe into an open region with a slow co-flow of air. Upon exiting the pipe, the syngas mixes and combusts with the surrounding air in a non-premixed manner. The resulting turbulent flame is attached to the burner head.

The model is solved by combining the Reacting Flow and the Heat Transfer in Fluids interfaces. The turbulent flow in the jet is modeled using the k-ε turbulence model, and the turbulent reactions are modeled using the eddy dissipation model. The resulting velocity, temperature and species mass fractions in the reacting jet are compared to experimental values.
