Turbulent flame propagation, scalar turbulence.

It brings me great joy to study the theory of turbulent flames. Certain basic questions remain open in this topic. For example: does the shape of a turbulent flame determine its overall burning rate under all circumstances? In general, what are the respective contributions of the external (topological) and the internal (thermo-chemical structure) aspects of a turbulent flame to its propagation and survival? It is also, as yet, unclear how during the course of its propagation the flame responds to and affects the turbulence itself.

I am interested in developing physical descriptions that address such questions by relying on mathematical analysis, computer simulations, and by engaging with experimentalists. The research is pertinent to flames in domestic stoves, automotive engines and gas turbines, as well as to type 1a supernovae.
