Surface property analysis of 3D turbulent Bunsen and spherically expanding flames

We have obtained time-resolved, 3D flame surface data (corresponding to an isotherm) for 3D turbulent flames on a Burner stabilized flame, as well as for a spherically expanding flame. We have explored some of the properties of these flames, but more information is desirable.

Objectives:

• characterize of the length scale of the flame structures, and comparison of those to turbulent length scales
• obtain of the pdf of the instantaneous total area of the flames and relate it to existing turbulent theories
• obtain of the time and space frequency content of the structures, which can be related to either hydrodynamic instabilities or turbulence.

Requirements: interest in turbulent flows, combustion, signal processing, pattern recognision and algorithms. Good proficiency with Matlab and/or Python.
