Cette thèse présente une nouvelle approche d’allumage des foyers aérobies basée sur le retournement temporel microonde. Dans la première partie on montre les bases de la théorie de combustion diphasique, le système d’allumage classique qu

The thesis is addressed to the study of physical issues related to the “Shock Ignition” (SI) approach to Inertial Confinement Fusion (ICF). In particular, because of the high laser intensities, a copious amount of hot electrons (HEs) are generate

Solid rocket motors (SRMs) use the combustion of a solid material, the propellant, as an energy source.A crucial step in the operation of such an engine is its ignition, during which the surface of the propellant must be heated by about 400 degrees t

Low vulnerability gun propellants are energetic materials specifically designed to resist unintended initiation stimuli and aim at replacing the usual nitrocellulose (NC) based ones. The different phenomena involved in the propellant’s ignition are

À ses débuts, la conquête spatiale a pu bénéficier des rivalités politiques de la Guerre Froide pour se développer rapidement sans réellement se soucier des efforts économiques à fournir. Aujourd’hui, de nombreux pays subissent le revers

Car manufacturers aim to develop new technologies for reducing the CO2 emissions of Spark Ignition (SI) engines as emission regulations get increasingly stringent. One of the solutions found by the car manufacturers is the downsizing concept applied

This study presents a semi-empirical modeling approach based on an extensive parametric study using a spark-ignition port-injection engine. The experimental results are used to derive engine-out emission models for each regulated pollutant (CO, HC, N

Internal aerodynamics is a key element for improving the combustion efficiency in Spark-Ignition (SI) engines. Within this context, CFD tools are increasingly used to investigate in-cylinder flows and to support the design of fuel-efficient engines.

Homogeneous lean combustion is a great opportunity to reduce Internal Combustion Engine (ICE) emissions (both greenhouse gases and pollutants) if combined with responsible use. Unfortunately, burning lean mixtures and meeting the demands of ICEs is c
