Testo completoThis thesis investigates the use of dynamic transport simulations to evaluate urban mobility policies, focusing on ride-sharing and Low Emission Zone in the Paris metropolitan area. It relies on two transport simulators: the existing METROPOLIS1 and METROPOLIS2, a novel simulator developed as part of this PhD. Both simulators employ discrete-choice theory to estimate responses of commuters to policy changes and assess the impact on utility. Using a mesoscopic framework, the simulators efficiently model road congestion at the city and regional scales. METROPOLIS2 builds upon its predecessor, enabling the evaluation of a broader range of policies, such as vehicle-based restrictions, with enhanced efficiency and accuracy.The first chapter explores a ride-sharing scheme with inflexible drivers who maintain fixed departure times and routes regardless of whether they carry passengers. METROPOLIS1 is used to model the departure time and route chosen by each commuter, as well as the resulting congestion levels. The optimal matching of drivers with passengers, as well as the pick-up and drop-off points, are obtained by solving an integer linear programming problem. Simulations of Paris's morning commute demonstrate that, even with low participation, ride-sharing can reduce congestion, fuel consumption, and CO2 emissions. Additional benefits can be achieved by increasing vehicle capacity or offering monetary incentives, without compromising driver inflexibility.The second chapter introduces METROPOLIS2, a mesoscopic agent-based transport simulator capable of modeling travel decisions (mode, departure time, and route) based on discrete-choice theory within a dynamic, continuous-time framework. The simulator improves upon its predecessor METROPOLIS1 by incorporating trip chaining, multiple vehicle types, greater flexibility in utility specification, etc. Its efficiency and accuracy are validated through two case studies: replicating analytical results from the standard single-road bottleneck model and demonstrating superior speed and convergence compared to its predecessor on a large-scale scenario of the Paris region.The third chapter applies METROPOLIS2 to evaluate the Low Emission Zone (LEZ) in Paris. Open data are used to generate a synthetic population and road network, while machine-learning techniques (such as Lasso regression and Bayesian optimization) calibrated the simulation to replicate observed travel times and behaviors. The analysis assesses the LEZ's effects on air quality, congestion and inequalities, highlighting benefits for city-center residents but revealing potential disadvantages for suburban populations dependent on older vehicles

Testo completoIn this thesis, we have studied two catalysed systems for low emission vehicles: the fuel cell supplied with reformate and the NOx trap for Diesel engine after-treatement. Despite their different functions powertrains, these two systems have in commun the need for monitoring the level of stored pollutant on the catalyst in order to optimize their efficiency. Due to the similarity of the equations involved, the same strategies of control can by applied in the two technologies. A fuel cell is a system which converts chemical energy into electricity with very low emissions. The mathematical modeling of the eletrochemical and thermal phenomena of the fuel cell supplied with reformate leads to a reduced model which was validated on experimental data and applied to the observation, the fault detection and the control of fuel cell carbon monoxide poisoning

Testo completo"Dioxins" (PCDD/F) are persistent organic pollutants which are emitted in the atmosphere by several combustion and thermal processes. The present study concerns the oxidation and the pyrolysis of dibenzofuran which is chosen as a model molecule of polychrorodibenzofurans. The reaction is studied at very low concentration of dibenzofuran (~2 ppm) in a continuous perfectly stirred reactor between 3s and 5s, whereas temperature is ranging from 500°C to 950°C. During dibenzofuran decomposition, several intermediary species are formed; they are identified by GC/MS and then quantified by TD/GC/FID. The main products are derivatives of benzofuran, polyaromatic hydrocarbons and other volatile organic compounds. Taking into account our experimental results and the literature data, we have proposed and validated a detailed mechanism of DBF reaction. This mechanism is used to model the abatement of dioxins by total oxidation in the postcombustion area of a municipal waste incinerator

Testo completoThe objective of this thesis is the conception and testing of a device which promotes the heat flux of a double-wall for low emissions combustion systems. The literature study prevailed the use of Offset Strip Fins (OSF) as heat flux promoter. Three double-wall with OSF have been tested in a combustion test cell equipped with: gas analysers, for calculating discharge coefficients, pressure sensors, thermocouples, and infrared thermometry. Velocity measurements on a 40 scale OSF also have been obtained by using Laser Doppler Anemometry. A simplified 1D model, capable of calculating temperatures profiles or analysing the experiments, is presented. The comparisons between the experimental results and the 1D / 3D RANS Fluent calculations permitted the evaluation of the Manglik & Bergles correlations concerning the pressure drop and the heat transfer coefficient of heat exchangers of the type OSF. After presenting the specific methodology of analysis a new correlation is derived

Testo completoIn urban areas, atmospheric pollution represents a major threat to human health. The accurate characterization of this threat relies centrally on the quality of exposure assessment. It also requires assessment of other factors sharing the same sources and also possibly impacting health, such as noise. Fine-scale exposure assessment of air pollution levels may allow identifying spatial contrasts. Such spatial variations may lead to social differences in the distribution of the health impact of these pollutants.The general aims of the PhD were: 1. To study the possibility to model ultrafine particles distribution in urban areas and assess the correlation of ultrafine particles levels with road traffic noise; 2. To assess the risk incurred by air pollution exposure with a fine-scale modelling approach and investigate the potential socio-economic disparities in health burden induced by particulate matter; 3. To investigate the health benefits expected from hypothetical scenarios of reduction of air pollution levels at the urban scale.The first aim relies on Tri-tabs project, conducted in three European cities (Basel, Girona, Grenoble). Measurements during 20 minutes of outdoor noise and traffic, but not of UFP, were strongly reproducible over durations of a couple of days or months. In these areas, on the short-term, noise levels and UFP concentrations exhibited relatively moderate correlations, which may allow adjustment for mutual confounding in epidemiological studies, thus allowing to disentangle their possible short-term health effects.The second aim introduces health effects, and focuses on the longer term. Risk assessment studies often ignore within-city spatial variations of air pollutants. In Grenoble and Lyon areas (0.4 and 1.2 million inhabitants, respectively) in 2012, PM2.5 exposure was estimated on a 10×10 m grid by coupling a dispersion model to fine-scale data on population density. Outcomes were mortality, lung cancer and term low birth weight incidences. The numbers of cases attributable to air pollution were estimated overall and stratifying areas according to the European Deprivation Index, a measure of social deprivation. Estimations were repeated assuming spatial homogeneity of air pollutants within city. The proportion of cases attributable to air pollution was in the 3-8% range for mortality and 9–43% range for term low birth weight. In Grenoble, 6.8% (95% CI: 3.1–10.1%) of incident lung cancer cases were attributable to air pollution. The impact was underestimated by 8 to 20% when background monitoring stations were used to assess exposure, compared to fine-scale dispersion modeling. Health impact was highest in neighborhoods with intermediate to higher social deprivation.Several countries across Europe have implemented air pollution regulation policies, or low emission zones, France being an exception. We estimated the health impact of air pollution under different scenarios of reduction of fine particulate matter concentrations. Scenarios targeting a reduction in the PM2.5 annual averages by 5% led to a 10% decrease of the health burden, while actions aiming at only reducing the exposure of the population exposed above the 90th percentile did not yield a significant reduction of the health burden (around 1%).In conclusion, we have shown that short-term measurements cannot be used to model ultrafine particles levels in urban areas; we were among the first to rely on a fine-scale exposure model for estimating the health impact of air pollution, and quantify its impact on term low birth weight. Our estimations showed that background air quality monitoring stations used classically in France for health impact assessment studies tend to underestimate exposure, compared to a spatially-resolved dispersion model. We have provided an estimate of the air pollution decrease required to obtain a significant reduction of the health impact of air pollutants in urban areas
