Description of the thesis topic

The characterization of the production of nano-particles generated by turbulence flames represents a societal and industrial challenge. On the one side, many practical systems emit soot into the atmosphere as a result of incomplete combustion of hydrocarbons. This pollutant emission is characterized by a distribution of solid carbon particles with different sizes and shapes, which have negative effects on human health and environment. On the other side, the creation of new materials from nano-particles is a growing market with applications in transport, construction, energy and communications sectors.
The control of nano-particle emissions is then essential for environmental and economical issues and progress in numerical simulations is essential to the successful design of controlled-emission combustion systems. Unfortunately, the Large-Eddy Simulation (LES) approach, which has successfully demonstrated its capacity to represent gaseous turbulent combustion processes, is far from being predictive for solid particles emission. This is mainly due to the fact that nano-particles production in turbulent flames is far from being a well-known process and many efforts are still needed in terms of characterization and modeling in this topic.
In this context, the goal of this PhD thesis is to provide new insights on the processes governing nano-particles production in turbulent flames through novel well-controlled experiments or high-fidelity numerical simulations.

Work Context

This work is supported by the ERC Starting Grant 'SOTUF' (http://em2c.centralesupelec.fr/en/ERC_Sotuf), supervised by Dr. B. Franzelli (http://em2c.centralesupelec.fr/Benedetta_Franzelli). The successful candidate will integrate the 'turbulent combustion' team at EM2C laboratory. He/she will have access to the most advanced experimental equipment and numerical solvers for the investigation of solid particles production in turbulent flames. He/she will also profit of the presence of many experienced researcher scientists (Dr. C. Betrancourt, Eng. P. Scouflaire, Dr. Denis Veynante, Pr. N. Darabiha and Pr. S. Candel).

Constraints and risks

Applicants for PhD appointment will hold a M.Sc. degree in Mechanical Engineering/Energetics. The position requires:
• Strong skills in Fluid Mechanics, Turbulence, and Thermodynamics.
• Strong willing to develop experimental or numerical skills in the combustion field.
• Good oral and written communication skills to report, to present in congress and to write articles for scientific journals.
