Étude expérimentale et modélisation des pertes thermiques pariétales lors de l'interaction flamme–paroi instationnaire

Abstract : Throughout this work, unsteady flame–wall interaction is studied experimentally in both laminar and turbulent regimes, in order to improve current knowledge and provide reference data for modelling and simulation. First, an equation for thermal head-on flame quenching is derived from the energy balance in quenched zone. Based on heat conduction, this model is confirmed by simulating the combustion of gaseous mixture in a spherical vessel. Additionally, a model for wall heat losses is developed in collaboration with RENAULT, based on a new approach of heat conduction resulting from gas–wall collisions. This model is validated in both laminar and turbulent regimes, and improved in order to account for the influence of gas dynamics on wall heat losses in combustion chambers.
