The TNF Workshop series facilitates collaboration and information exchange among experimental and computational researchers in the field of turbulent combustion, with an emphasis on the interactions of turbulence and chemistry in flames with well-defined boundary conditions.


The 1st TNF Workshop was held in Naples, Italy in July 1996, before the 26th Combustion Symposium, with a purpose of identifying experimental data sets and establishing guidelines for collaborative comparisons of measured and calculated results. Subsequent workshops were held in Heppenheim, Germany (1997), Boulder, Colorado (1998), Darmstadt, Germany (1999), Delft, The Netherlands (2000), Sapporo, Japan (2002), Chicago, Illinois (2004), Heidelberg, Germany (2006), Montreal, Canada (2008), Beijing, China (2010), and Darmstadt, Germany (2012). Proceedings are available through the TNF Workshop home page.


  • Provide an effective framework for comparison of measured and modeled results.
  • Establish a series of benchmark experiments and calculations that cover a progression in geometric and chemical kinetic complexity across a range of combustion modes and regimes.
  • Understand the capabilities and limitations of various combustion models and submodels.
  • Identify priorities for further collaborative research.

We emphasize that this is not a competition, but rather a means of identifying areas for potential improvements in a variety of modeling approaches. This collaborative process benefits from contributions by participants having different areas of expertise, including velocity measurements, scalar measurements, computational methods, turbulence modeling, chemical kinetics, reduced mechanisms, mixing models, direct and large-eddy simulation, radiation, and combustion theory.
