TNF18 is expected to be held as a satellite workshop of the 42^nd International Symposium on Combustion in Rio de Janeiro, Brazil, 23-28 July 2028.  

The Organizing Committee expects that the main emphasis of the workshop will be on collaborative comparison of LES results against experimental/DNS dataset on selected turbulent target cases involving premixed and multi-regime combustion of hydrogen and blends of hydrogen and ammonia or methane.  Many of the available experimental and DNS datasets already have brief descriptions on the TNF website (see below), and data archives for some cases can be downloaded.  Additional descriptions and data will be added as they become available. 

It is essential that the targets for collaborative comparisons be selected well ahead of the workshop to allow for coordination among the participating groups.  We anticipate that there will be an email broadcast early in 2027 to update the community regarding available datasets and to gauge interest in some of the more likely targets for TNF18.  We also anticipate that there will be an email broadcast in summer 2027 (if not before) to identify specific target cases for comparative simulation and to begin coordination among the interested group.  Those interested in participating in collaborative model comparisons are encouraged to contact the data owners or corresponding members of the TNF Organizing Committee.
