Dynamic surface analysis of 3D turbulent Bunsen and spherically expanding flames

We have a dataset of time-resolved, 3D flame surface data (corresponding to an isotherm) for 3D turbulent flames on a Burner stabilized flame, as well as for spherically expanding flames. 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 in 2D and 3D, and comparison of those to turbulent length scales
• obtain of the time and space frequency content of the structures using Fourier and other transforms, in order to relate the frequency content to either hydrodynamic instabilities or turbulence.

Requirements: interest in fluid mechanics, signal processing, pattern recognition and algorithms. Good proficiency with Matlab and/or Python.
