Turbulent flames

Cambridge-Sandia Swirling Stratified Flames

How do turbulent flames propagate through mixtures that are not uniform ? Our previous work on understanding the behaviour of turbulent flames, in collaboration with Sandia National Labs, has shed light on a number of aspects of such flames, and ultimately showing that flames are primarily sensitive to the local equivalence ratio rather than the surrounding gradients.

A database of results for the Cambridge-Sandia flames can be found in the Database section.

Oxycoal flames

We have developed some of the first experiments on oxycoal flames, to understand how CO2-O2-coal flames burn in the laboratory at conditions similar to what can be found in real flames.

A database of results for the coal flames can be found in the Database section.
