A study on the effect of turbulence on premixed flames, which was done by Professor M. Matalon, his postdoc F. Creta and graduate student N. Fogla, is featured in a recent cover article of Combustion Theory and Modelling.
The picture on the cover, obtained by numerical simulation, shows the polyhedral-cellular structure that develops on the surface of a flame propagating in a combustible mixture that is subject to turbulence. The wrinkled flame, which is characterized by smooth protrusions towards the fresh mixture separated by sharp crests towards the burned gas arranged in web-like fashion, bear a striking resemblance to those observed experimentally on the surface of expanding flames.
