Zhu, Xiaoxiao. "Influence of hydrodynamics and correlation of metal contents with settling velocities on contamination distribution in a stormwater detention basin." Thesis, Lyon, 2019. http://www.theses.fr/2019LYSEI035.
Stormwater detention basins have three main functions: storing rainwater to prevent flooding, promoting settling of particulate pollutants, avoiding resuspension and remobilization of settled pollutants to the downstream. The design and the management of such facilities requires the knowledge of hydrodynamic and sediment characteristics, as well as the ability to predict areas where deposits are highly contaminated.The main objective of this PhD work is to identify the areas where pollutant levels in sediments are high in detention and settling basin. The studied site is the stormwater detention basin (Django Reinhardt basin or DRB), which is an extended and dry basin at the outlet of an industrial watershed. This basin has been the subject of numerous investigations within the framework of the Field Observatory for Urban Water Management (or observatoire de terrain en hydrologie urbaine - OTHU in French).First of all, the measurements of surface velocities by Large-Scale Particle Image Velocimetry (LSPIV) permits to better understand the hydrodynamic behaviour in the basin. These measurements were used to evaluate CFD (Computational Fluid Dynamics) models. This is the first time this measurement technique has been applied in the case of stormwater management facilities. The results show that CFD models identify the main recirculation zone that promotes settling. These evaluated models were then used to simulate the transport of particulate pollutants, including sedimentation and resuspension. The exploitation of these simulations results enables to (i) identify the preferential areas where resuspended contaminated sediments may be conveyed to the downstream infiltration basin and (ii) predict the accumulation zones of some metals. Results also demonstrate that iron contents in sediments are strongly correlated to settling velocities and can be considered as a good indicator of the level of heavy metals contamination of sediments. The results obtained in this thesis contribute to improve the design of stormwater detention and settling basins and the management of contaminated sediments

Road transportation is a major contributor to air quality pollution in urban areas, particularly in fine and ultrafine particles. These pollutants are harmful to human health, as they can worsen or cause lung and cardiovascular diseases. In this context, we are interested in the evolution of particles emitted from heavy truck exhausts, starting from their emission. The main objective of this thesis is to study the extent of particle dispersion emitted by heavy truck's exhausts, around and in the wake of heavy trucks. Numerical methods based on an Euler-Lagrange approach were used to simulate and characterize the airflow topology around the truck, using the Reynolds-Averaged Navier-Stokes (RANS) method for the fluid phase and a Lagrangian approach for the dispersed phase. These simulations were supported by wind tunnel measurements in the wake of a reduced-scale model of a heavy truck. Particle Image Velocimetry (PIV) was used for analyzing the air velocity fields, while the dispersion of ultrafine solid particles was characterized by measuring concentration fields using a granulometer. The truck's wake flow is completely detached at the rear of the trailer, revealing a recirculation zone mainly composed of a large vortex, coming from the under-trailer. Particles' dynamics appears to be dominated by turbulence and strongly correlated with vortical structures, especially in the wake of the truck. Indeed, particles tend to concentrate preferentially on the periphery of the main vortex formed behind the truck, as well as in areas of low turbulent intensity. The movement of most inertial particles (diameter > 2.5~mu m) is dominated by gravity, while turbulence is mainly responsible for the movement and deposition of the finest particles (diameter < 2.5~mu m). The position and orientation of the exhaust pipe also have a significant influence on the extent of dispersion and the distribution of particles in the underbody and in the wake of the heavy truck. Indeed, when particles are emitted from the under-trailer, most of them are concentrated in the recirculation zone, less than 1.85H away from the trailer (H being the height of the trailer), and at human height. On the other hand, the particles emitted on the top of the truck are very rarely re-entrained in the recirculation zone, and are mostly concentrated above it, at a height equivalent to 2.6~m (0,9H) above ground level. The exposure of populations to the particles emitted by heavy goods vehicles could therefore be sharply limited when the exhausts are released from top of the truck

Living in an environment filled with air pollution will affect our body health, cause chronic illness, and increase the fatality rate. However, it is difficult to regulated air pollution effectively, due to the need to accurately gathering evidence to prove any illegal emission. In this research, we propose a method to exploit the ability of a drone to locate air pollution (i.e., particulate matter) emission source quickly. Utilizing the information provided by an existing sensor network, the drone is able to make correct decisions when searching for pollution sources. In the proposed system, Location Aware Sensing System (LASS) provides the continuous monitoring information of PM 2.5 (Particulate Metter 2.5) to initialization searching plan by limiting a searching area. In the beginning, our drone utilizes the PM2.5 concentration information provided by LASS to adjust its searching direction and distance to an intermediate point. After an intermediate location point is reached, our drone will stop and sense the current PM2.5 concentration. Next, the drone continues to adjust the searching path with its searching direction and distance when the concentration level increased, respectively. The three searching path strategies are proposed - Greedy, Dynamic, and Hybrid Approach. The searching process repeats itself until ten of the continuous sensed PM2.5 concentration levels dropped below a threshold or the power of drone fell lower than the maximum flight time (with the reserved power for the return home distance). Once the searching process is finished, the location of the air pollution emission source is estimated by the highest contraction level measured by drone. The three of proposed strategies are compared with Random Way-Point and Space-Filling Curve. Experiment results show our proposed techniques are able to achieve estimation error below 2 meters within 20 minutes.
