Etudes expérimentales et numériques d'un jet de particules : application au freinage ferroviaire

Abstract : Urban railway transportation, although regarded as an sustainable alternative to individual transport, is now the subject of growing interest in health risk and exposure to fine particulate matter. Measurements of fine particulate matter (PM) in several underground networks of worldwide cities have revealed relatively high levels. These measurements are based on average rates measured mainly in stations and do not make it possible to identify precisely the origin of the particles. The main objective of this work is to provide experimental data to improve numerical predictive models of transport and particle behavior resulting from the braking of rolling stock. This contribution aims to numerically test the "Suspension balance Method" (SBM), method based on the phenomena of migration of particles in a flow. A canonical configuration of flow is defined (jet of particles in boundary layer) in order to carry out an experimental validation by optical methods. These tests are carried out in a hydraulic channel with injection of calibrated particles.
