Abstract
The TECFLAM configuration is a lean premixed methane-air burner with a high swirl intensity where the flame is stabilized by the recirculation of hot products. It is designed to investigate essential features found in industrial lean premixed combustors. An extensive set of measurements obtained by advanced laser-diagnostics exists to:
- Give insight into the underlying physics to gain a deeper understanding of the relevant phenomena
- Build a database well suited for CFD validation
Validation data is available for the reacting and non-reacting cases using the same velocity boundary conditions to allow for a separate assessment of the applied turbulence model and combustion model. A total of four cases are considered in this AC consisting of a 30 kW and 150 kW flame and their corresponding isothermal cases.
