Exploring the potential of electrostatic precipitation as an alternative particulate matter filtration system in aircraft cabins.

On most modern airliners, cabin air pressurization, heating, and renewal are mainly achieved using air supplied from the gas turbine engines during flight. This air intake impairs the motors yield and needs to be conditioned, leading to energy overconsumption. Recent advances in thermal management enable aircraft manufacturers to reduce further the intake airflow needed to maintain cabin temperature at high altitude.

Characterization of two-phase flow regimes in horizontal tubes using 81mKr tracer experiments.

The diagnosis of heat exchangers on duty with respect to flow mal-distributions needs the development of non-intrusive inlet-outlet experimental techniques in order to perform an online fault diagnosis. Tracer experiments are an example of such techniques. They can be applied to mono-phase heat exchangers but also to multi-phase ones.
