Flux critique

Summary : The study of rapid transient boiling is an important issue in the nuclear safety. Such a phenomenon may occur in the case of a RIA (Reactivity Initiated Accident) in the core of a nuclear reactor powerplant, where a power excursion can trigger the formation of a vapour film around the fuel rod, leading to an important rise of the rod temperature and a risk of failure. Some studies in reactor conditions provided transient boiling curves but the modeling lacks of reliability.

Summary : This thesis is part of the industrial context of rapid development of electric vehicles, which includes the growing demand for more powerful and compact battery packs. These packs are generally made with lithium-ion battery cells and require a Battery Thermal Management ...
