British-Spanish-Portuguese Meeting on Combustion

Fitzwilliam College at Cambridge, hosted the joint meeting of the British, Portuguese and Spanish Sections on 12-14 April. The meeting followed the same mini-symposium format of the joint British and Scandinavian meeting in 2014.

Prof. Amable Liñan, from the Spanish Section, kicked off the meeting with developments on flameless combustion and explosion limits on spherical vessels. The former Zeldovich medal winner illustrated the theoretical insight from relatively simple flames and the importance of understanding fluid and chemical scales. Prof. Nilanjan Chakraborty, from the British Section, was the second invited speaker.  He presented how turbulence premixed-combustion models can be validated using DNS. He showed the changes on the flame characteristics caused by the Lewis number and suggested that long-held views on turbulent flame propagation may have to be revisited.

Following the mini-symposium format, the meeting ran two parallel sessions both days.  The first session targeted research on sprays and droplets, followed by fuels and chemical kinetics.  The other session focused on DNS of turbulent flames. In the second day, there were sessions on diagnostics, biomass combustion, combustion instabilities and particles.  The presenters were a mix of PhD students and more experienced researchers. The format of the meeting gave the students an opportunity to taste a “real “conference. The meeting also included a small presentation from Elsevier, targeted at student and early researchers, on academic writing.

The talks showcased the strong research being carried out in the different sections and the trends of the combustion community. Following the current research climate, biomass and fuel blends were strongly represented. The numerical simulations presented showed the ever-increasing sophistication of CFD, both in complexity and possible applications. Large Eddy Simulations techniques are becoming more standard and they were examples from both sections on applications to industrial configurations. Several speakers showcased the latest attempts to perform simulations with large chemical mechanisms; either using reduced chemistry or intelligent tabulation. New applications presented included soot modelling as well as thermo-acoustics instabilities. Although numerical techniques probably dominate the meeting, there were also presentations on theoretical analysis and diagnostics developments. Overall, the meeting was a good snapshot of combustion research in 2016.  It showed the similarities and differences between the sections. The attendees generated interesting discussions and hopefully created future collaborations. The chosen mini-symposium format was successful and hopefully there will be many similar meetings to come.
