The research professions professional group is pleased to invite you to its fourth conference on Thursday, November 3, 2016 at 7:00 pm at Maison des Ponts:

Research facing the challenges of aerospace propulsion

with

SébastienCandel
Vice-President of the French Academy of Sciences for 2015-2016

At a time when ecological constraints on transport and industrial activities are becoming ever more pressing, air transport - which only emits around 2.5% of the world's polluting emissions, but is a fast-growing sector (+5% traffic growth per year on average) - has to cope with increasingly restrictive standards. One of the ways of optimizing pollutant emissions, over and above indirect sources such as aircraft load factors or electric taxiing, lies directly in engine design. Research is therefore needed to improve engine thermodynamic modelling, or to design ever lighter and stronger materials. Sébastien Candel will present the latest advances in combustion research, the fundamental building block of aeronautical propulsion , andshow how these advances can be implemented in collaboration with industry.

Sébastien Candel

Sébastien Candel is Professor Emeritus at École Centrale Paris and Honorary Member of the Institut Universitaire de France. A specialist in the fields of combustion and aeroacoustics and their applications to energy and aerospace propulsion, Sébastien Candel's research addresses a series of fundamental questions. His contributions focus on flame structure, ignition and extinction, interactions between flames and vortices, and turbulent combustion, with the development of models based on flame surface density balances, which are widely used in practice. His work in combustion dynamics focuses on instability mechanisms, leading to a unified description of limit cycles, non-linear triggering and mode switching, with applications to gas turbines and rocket engines. Innovative concepts are proposed for active or dynamic flame control. In cryogenic combustion, his studies give access to fundamental mechanisms and stabilization criteria, and lead to the development of appropriate large-scale simulation methods. His research into numerical simulation of combustion covers averaged modeling, direct simulation, stabilization and acoustic coupling. His work in aeroacoustics has led to the identification of mechanisms generating aerodynamic noise, the development of calculation methods for acoustic propagation in moving media, and the elaboration of noise estimation methods applicable to aircraft and Ariane launchers at take-off.

A cocktail will be served at the end of the conference (10 euros for Ponts Alliance members, 20 euros for non-members).
