Dear Colleagues,


The Sixteenth International Workshop on Premixed Turbulent Flames (PTF-16) will be held at the Trinity College Arts Building in the Swift class room, Nassau Street, Dublin, Ireland, starting at 9 am on Friday and Saturday (July 27th and 28th, 2018) just before the 37th Combustion Symposium.  


The registration fee will cover lunches on Friday and Saturday. For those who choose to stay for dinner on Friday there is an additional charge. All meals in Dublin will be served in a large room next to the five workshops that are being held in adjacent rooms in the Arts Building. Not all workshops run at the same time, but there will be significant overlap. As we did last time, the plan is for PTF-15 to run from 9:00 – 17:00 on Friday and Saturday.


A unique aspect of our PTF workshop is that each presentation is limited to 10 minutes, which is followed by a discussion period that may be 15 minutes. Some previous topics:

Flamelet Structure       Numerical Simulations   Data bases               New Diagnostics

Burning Velocities      Flame Dynamics             Partially-premixed  Combustion Instabilities                                             

1.     What can we decide for certain, what is a research issue ?

2.     Tabulation and comparisons of experimental and DNS data bases

3.     New answers can be obtained using kilohertz diagnostics ?

Attached is a list of talks given at the last workshop (in Seoul).
