Combustion in Gas Turbines

Investigations in low TRL reactive flow processes in combustion chambers

Introduction

This research area focuses on the analysis of combustion process in gas turbine engines delving into the fundamental phenomena related to the liquid spray atomization evaporation and mixing, as well the reacting flow evolution, flame stabilization and pollutant formation. A combination of unique experimental environments, advanced optical diagnostics and detailed numerical models provides synergetic results that can help evaluate industrial relevant configurations. Particular attention is paid to low carbon solutions for aeroengines, such as hydrogen, ammonia and sustainable aviation fuels
