Der volle Inhalt der QuelleCrystallization is influenced by several parameters such as supersaturation, temperature, environment, and hydrodynamics. Thus, a rapid screening of crystallization conditions is often required during the study of the crystallization of a molecule. But when a small amount of material is available, a suitable experimental tool is essential. In our case, the microfluidic system dedicated to crystallization is based on the generation of nanoliter droplets in which crystallization can occur independently. Forming hundreds of droplets with monodisperse sizes and experimental conditions, we can make a large number of experiments per condition for statistical studies to meet the stochasticity of the phenomenon of nucleation while consuming little material. Our goal is to create a universal microfluidic assembly which is compatible with all solvents and molecules. Thus, we are interested in simple microfluidic junctions and tubings which is resistant to many solvents. From such systems, we have first characterized the hydrodynamic properties of the set-up: we sought to control microfluidic flow and reduce the volumes put-in. We studied the droplet generation regimes and the scaling law of drop size and frequency. For crystallization study of biomolecule, we have validated our microfluidic set-up for crystallization studies in a viscous media, on the recombinant urate oxidase or the rasburicase in an aqueous solution of PEG. Finally, we integrated a module for on-line characterization of each droplet’s chemical composition

Der volle Inhalt der QuelleSolute transport coupled with biofilm growth in porous media is encountered in many engineered applications, for instance biofiltration of wastewater and air pollutant treatment. In terms of modelling, the interaction between biology, hydrodynamic and chemistry are still difficult to understand at the fine scale: that led to a wide dissemination of macroscopic model, simpler to handle. However, one issue consists in providing a macroscopic model complex enough to take into account the relevant processes accounting for the coupling between the biomass development and system functioning, but simple enough for operational use. This thesis focused on few selected processes that influence the macroscopic behavior of such system. First, we investigated the permeability reduction modeling accounting for biofilm development. A model including two features that result in permeability reduction (pore radius reduction and pore plugging) was developed. This model was assessed in a wide range of experimental data. Another part of the thesis focused on the initial biomass attachment that is an important feature to characterize the system initial state. Following the concept that bacterial cell can be treated as soft colloids, a new correlation equation was developed to estimate the bacteria attachment efficiency. This correlation is based on the regression analysis of a wide range of experimental data of colloid deposition in various electrolyte conditions, flowrates and geometries of porous media. New dimensionless parameters have been introduced to represent the coupled effects of Derjaguin-Landau-Verwey-Overbeek (DLVO) forces, hydrodynamic forces and to account for geometry of porous media. These features were introduced in a 1D dimensional model that have been developed for the numerical simulation of solute transport coupled with biofilm growth. An important issue in this model was to properly represent biofilm detachment. Another distinctive feature of our model is an attempt to account for the “sloughing” process in modeling biofilm detachment. Sloughing is a different process than erosion which corresponds to a discrete removal of large fraction of biofilm. In this study, biofilm sloughing has been separately accounted in the numerical modeling porous media bioclogging. Biofilm sloughing was considered as a stochastic process and quantified by random generator. So this discrete events could be incorporated into other continuous processes to determine the biomass transfer from biofilm to the liquid phase. Numerical simulations have been performed using OpenFoam to implement the model. Simulation with and without the sloughing term were performed and discussed in the frame of available literature data

Der volle Inhalt der QuelleWe investigate experimentally the dynamics of a sphere near a textured wall in a viscous fluid. High frequency laser interferometry is used to measure small displacements of the sphere. The texture is comprised of arrays of micro-pillars, whose geometrical parameters are systematically varied in order to study their influence of the dynamics of approach, collision and rebound of the sphere. Under creeping flow conditions, the sphere velocity near the textured wall is increased compared to the case of a smooth wall, as a result of the modification of the lubrication force due to the texture. We describe this modification using several hydrodynamic models. An effective slip length over the pillar array is measured. At moderate Stokes number the sphere inertia is non-negligible and the sphere can either stick or bounce off the wall. The sticking dynamics exhibit several regimes which can be described by taking into account the modification of the lubrication force by the texture. The micro-pillars modify the critical Stokes number for the bouncing transition. The micro-rebounds are characterized. Finally, the contact dynamics between the sphere and the pillars are described by a Hertz law modified by the texture geometry

Der volle Inhalt der QuelleIn moderate pressure/low flow-rate diamond deposition plasma modeling, hydrodynamics effects are not taken into account. As a matter of fact, under these conditions, transport of the reactive species is mainly controlled by diffusion. However, when working at very high power density (high pressure and microwave power) and flow rates higher than 500 sccm, growth rate has been seen to be a function of the gas inlet and outlet set-up. In the context of this PhD, we have developed both a 2D axi-symmetrical and a full 3D models able to describe the hydrodynamic flow in PECVD (Enhanced Chemical Vapor Deposition) diamond reactors. Due to the complexity for developing a complete plasma model, we have strongly simplified the plasma description. On the one hand, a thermal source term able to simulate the plasma gas temperature spatial distribution has been defined, and on the other hand, the chemical kinetics scheme has been somewhat reduced. Comparisons between the results obtained by this new model with those provided by LSPM’s existing plasma models and the experimental results allowed us to validate our approach. The model correctly reproduces the thermochemical processes behavior. On this basis, new configurations for the gas inlet and outlet set-up using 3D simulations were conducted. Some were seen to be relevant for improving the diamond deposition process
