Texto completoThe primary objective of the thesis is to quantitatively assess the dynamic behavior of turbulent airflow around a NACA airfoil as a function of the upstream flow. The upstream flow consists of a family of coherent structures, each with its own distinct temporal and spatial scales. Additionally, this upstream flow may include a mean shear due to a large scale boundary layer. These situations are commonly encountered in wind and marine turbine farms, where the wake generated by one turbine becomes the upstream flow for the next one, and where the atmospheric boundary layer can influence the dynamics of the airfoil’s airflow. Aerodynamic research on wind turbines has primarily focused on the general response of airfoils, and the flow downstream. However, airfoils are not considered yet in an upstream flow with the presence of a family of coherent structures. This study takes into account the spatial and temporal aspects, which is crucial for understanding how efficiently the kinetic energy carried by these coherent motions is captured within the wake. The novelty of the project is to provide a complementary and more detailed analysis of the airfoil-upstream flow interactions based on the analysis of the intermittency of the upstream conditions. This helps to gain insights into the dynamic response ofthe downstream airfoil and the distribution of kinetic energy over the airfoil. To achieve this goal, pressure distributions (coherent structures) must be phase-averaged with a conditioning based on the dynamics of the upstream flow. This type of analysis representsa novel approach and requires the development of specialized methods to be applied to such complex cases. One of the key areas of investigation within the project is the study of the total turbulent kinetic energy (TKE) when the upstream coherent structure packets interact with the downstream airfoil. Additionally, further research can be involved into turbulent kinetic energy, considering the interactions between different components of fluctuations, such as the interactions between coherent and random motion. This thesis work is integrated in the framework of DYNEOL (ANR-17-CE06-0020) project that is funded by the French National Agency of Research (ANR). The project is a collaborative research involving four French laboratories, including the CORIA laboratory

Texto completoA main objective of this thesis is the physical analysis by solving the Navier-Stokes equations of flows around an airfoil at zero incidence for a viscous compressible fluid in the subsonic and transonic regimes. For Mach numbers 0. 2-0. 4 and Reynolds 104 we have analysed the evolution of the von Kármán instability by means of the Landau model with use of Mach number as parameter. This instability is found to be triggered by the compressibility effect. This study allowed the evaluation of the critical Mach number for the appearance of this instability. The second part of the study consists of the development of a numerical code for the prediction of the fluid domain motion following the dynamic mesh variation. The pitching irfoils flows studied show a good agreement with the other studies. This work is a first step towards a fluid-structure interaction code

Texto completoThis work deals with the experimental characterization of the vortex shedding from a circular cylinder between parallel walls. Two experimental measurement techniques were used for the investigation of the wake downstream the cylinder : the PIV (Images Particles Velocimetry) and the polarographic method, with circular probes mounted flush on one of the two parallel walls of the channel downstream from the obstacle. In parallel to this work, one developed a computational code for the inversion of the convection-diffusion equation, which is based on the sequential Beck algorithm, in order to determine the wall shear stress from the limiting current delivered by the probes. Its validation was carried out beforehand by measurements in a cone-plate rheometer. Thereafter, one studied the vortex shedding behind the circular cylinder by synchronized measurements between PIV and polarography. Measurements of PIV were used to characterize the various flow regimes, and to show the main differences between this case of the confined wake (for a blockage ratio of 1/3) and the case of the non-confined wake. Then, one studied the dynamic of vortex structures downstream the cylinder. The decomposition of the instantaneous velocity fields obtained by PIV in Proper Orthogonal Modes (POD) made it possible to follow their energetic distribution for the studied range of Reynolds numbers ( 50 ≤ Re ≤ 300 ). With this decomposition, it is possible to make an inhomogeneous filtering and to reconstitute filtered fields solved in time. Finally, a comparison between the results of PIV and of electrochemistry was carried out

Texto completoThe various experiments carried out have laid emphasis on the study of hydrodynamic spatio-temporal structures found in an offshore wind turbine’s mast, coupled to a cylinder, which will later on be used at the Courseulles-sur-Mer wind farm. The hydrodynamic analysis focused on the synchronization phenomenon between regular waves and the Von Karman Street generated by a current, behind two different vertical cylinders. A diagram showing the different synchronization regimes with respect to the frequencies of the waves and the amplitudes studied, has been drawn. In addition to the results obtained with regular waves, the synchronization phenomenon has also been analysed using irregular waves. In the case of irregular waves, the phase diffusion coefficient, K, has been used to explain the different frequency synchronization observed. After having studied the synchronization phenomenon, tests were carried out on the study of sediment transport (scour and ripples) under the effect of different types of flows in an environment close to a vertical cylinder. In parallel to the laboratory experiments, a numerical study has also been conducted by studying the DNS (Direct Numerical Simulation) of a steady flow of current around a vertical cylinder. In addition to that a more complicated flow of a steady current around a network of cylinders comprising of a series of 4 cylinders arranged in 2 rows (representing a network of wind turbine masts) have also been observed and analysed. After having studied the flow made up by a steady current, the olafoam solver was used to apply a flow made up of both currents and waves in an obstacle free environment with a smooth floor. The numerical results obtained close to the free surface have been found to fairly agree with the findings of other related studies conducted. We observed a reduction in the intensity of the surface current when the waves and the current propagate in the same direction

Texto completoRoad 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

Texto completoGalaxies are beacons in the Universe that allow us to understand the evolution of the distribution matter in all its forms. The study of galaxies at different epochs helps to understand how they organize at large scales (greater than inter-galaxies distance) but also how they formed, and formed their stars.At our cosmic epoch, galaxies that reside in the densest environments (clusters, groups) have very different properties compared to galaxies residing in less dense environments. This bimodality between 1) elliptical galaxies, massive, old and forming little stars in dense environments on the one hand, and 2) of spiral galaxies, younger and experimenting intense star formation in less dense environments indicates different evolutionary mechanisms and formation mechanisms.The study of galaxies in clusters reveals that they probably experimented intense star formation at redshifts z ~ 2, and points to a synchronous episode of star formation in the galaxies in the cluster, and of colossal proportions (~ 500 solar masses per year, to be compared with the average rate of star formation observed in the local Universe in the order of ~ 1-10 solar masses per year). But this phase still lack a direct observational conclusion, although recent observations in this direction.One possible way to search for these objects is to try to detect their emission in the far infrared, which traces directly star formation. This is what has been achieved with the Planck satellite. From Planck / HFI data, a team in collaboration with us extracted 2151 cluster candidates experimenting an intense star formation phase. A follow-up of 228 candidates was made with the space telescope Herschel / SPIRE, and revealed overdensities of red sources, compatible with a redshift distribution peaking around z ~ 2, and star formation rates of approximately 700 masses solar year.To better constrain the redshift of these candidates, study their contents in terms of stars, another follow-up on 80 candidates was conducted using the IRAC instrument on the Spitzer Space Telescope. My work focuses on the analysis and interpretation of such data.The wavelengths of the IRAC instrument (3.6 and 4.5 microns) are indeed tailored to detect a characteristic peak emission of stellar populations, to estimate the redshift and the stellar mass.My work revealed overdensities of red IRAC sources (z> 1.3) at the positions of the red SPIRE sources (z ~ 2 ~ 700Msol.an SFR), compatible with clusters or proto-clusters in an intense star formation phase. Estimates of photometric redshifts and stellar mass show that these objects are compatible with the progenitors of local clusters.These candidates, however, require confirmation, especially with obtaining spectroscopic redshifts. This work has already begun, and two candidates have already been confirmed at redshifts of 2.15 and 2.36 using the 30m / IRAM. Data obtained with the ALMA interferometer and NOEMA revealed that the SPIRE emission originates in some cases from several galaxies.These initial results are encouraging, but a study at other wavelengths (near infrared) is also needed to better constrain the content of our mass objects, and their star formation history. The data is already available on part of the smple, and analysis has begun
