Because combustion instabilities are highly unpredictable, it is necessary to quantify their probability of occurrence:

      1. Uncertainty Quantification in computational fluid dynamics for the assessment of thermoacoustic instabilities.

 The quality of the flame response model obtained by System Identification is essential for a reliable estimation of thermoacoustic instabilities.

      2. LES/SI to assess simultaneously both the response of the flame to upstream velocity perturbations and combustion noise.

 Since very recently, it is known that acoustic cavity modes are not the only ones excited by the flame:

      3. Intrinsic ThermoAcoustic (ITA) instabilities.

 Compact numerical and analytical modeling of the flame response, which is based on fundamental physical principles, is of great importance in combustion instability studies:

      4. G-Equation and the vorticity-stream function formulation.

 The interaction of acoustic – flame mechanisms encountered in spray flames is considerably more complex that in gaseous flames.

     5. Flame dynamics characterization of Spray Flames.

 All five projects make use of experimental data for validation, and numerical simulation for fundamental understanding of the corresponding physics. Analytical formulations are aimed specially at projects 3-5, where a rigorous understanding on the physical mechanisms involved is essential.
