Texte intégralA typical water round-nozzle jet for agricultural applications is presented in this study. The dispersion of a liquid for irrigation or pesticides spraying is a key subject to both reduce water consumption and air pollution. A simplified study case is constructed to tackle both scenarios, where a round dn=1.2 mm nozzle of a length Ln=50dn is considered. The injection velocity is chosen to be UJ=35 m/s, aligned with gravity, placing the liquid jet in a turbulent atomization regime. The flow is considered statistically axisymmetric. Experimental and numerical approaches are considered.An Eulerian mixture multiphase model describes the original two-phase flow. Several U-RANS turbulence models are used: k-ε and RSM; where special attention is taken to the modelling of variable density effects from the mixture formulation. A custom numerical solver is implemented using the OpenFOAM CFD code. A series of study cases are constructed to test the influence of the turbulence modeling and first/second-order closures of the turbulent mass fluxes. LDV and DTV optical techniques are used to gather statistical information from both the liquid and the gas phases of the spray. The experimental campaign is carried out from x/dn=0 to x/dn=800. Concerning the LDV, small (~1 µm) olive-oil tracers are used to capture the gas phase, where a distinction between the liquid droplets and tracers is achieved by a specific set-up of the laser power source and the burst Doppler setting (BP-Filter and SNR). On the dispersed zone, DTV measurements are carried out to measure velocities and sizes of droplets. Special attention to the depth-of-field (DOF) estimation is taken in order to obtain a less biased droplet’s size-velocity correlation.Numerical and experimental results show good agreement on the mean velocity field. A strong dependence on the turbulence model is found. However, the RSM does not capture the same behaviour on the calculated Reynolds stresses. Indeed, neither the experimental anisotropy (R22/R11≈0.05), nor the liquid-gas slip-velocity can be reproduced, even with a second-order closure for the turbulent mass fluxes. The strong density ratio (water/air), flow’s directionality and production of turbulent kinetic energy may be the cause of a weak dispersion and mixing between the two fluids. This mechanism is not yet clarified from a RSM modeling point-of-view

Texte intégralLiquid-liquid dispersions and emulsions are formed in a large number of industrial domains, as well as in a wide range of products. However, their development presents one of the most complex operations. Dispersions are highly dependant on the physicochemical properties of products used and the hydrodynamics in the apparatus, which makes the prediction of the dispersion characteristics, and in particular, the optimization of the process, extremely difficult. This thesis investigates two types of liquid-liquid dispersions. Each type is discussed via separate case studies both created in an agitated vessel. The first case investigates an extraction operation, while the second concerns emulsions manufacturing, where by the drop size must be controlled. According to the nature and the complexity of the phenomena considered, two different approaches have been developed. In the first case, an experimental approach has been employed in order to optimize the yield in the purification step of a multi-functional acrylates process. The results show that there are predominant influences of certain operating parameters. It argued therefore that there is a need to develop a new process which considers environmental and economic requirements. In the second case, the development of emulsions with particular properties was investigated. The case adopts a synthetic approach that is based upon coupling a neural network and a genetic algorithm. Neural network is used as a non-linear modelling tool to determine the functional relationships between the means drop diameter and different operating variables. The genetic algorithm is used as a means for prediction the operating conditions that enable a given criteria (d32) to be reached. The application of these tools in the physical domain studied was shown to be of great interest. It is anticipated that such tools will lead to the development of new ways to control complex processes

Texte intégralThe aim of this work is to study a powder/liquid system for instantizing a powder in a liquid. The model powder chosen, cocoa, and its interaction with water were characterised to determine the dispersion behaviour. Contact angles and adhesion forces were measured by the sessile drop method and by a modified Washburm method. Water is a non-wetting liquid with respect to cocoa powder. Dispersion kinetics were measured by using an optical fibre detector. The most significant parameters on dispersion speed were the power of the agitation and the rise in temperature. Granulated powder was prepared by two processes : atomisation and high shear granulation. Atomisation lead to better dispersion while high shear granulation gave granules having an increased speed of dispersion

Texte intégralThe present thesis work concerns materials made of dispersions of nanometric colloidal particles, from a bulk ferroelectric material, dispersed within a chiral smectic phase of a ferroelectric liquid crystal. The goal of this work is to study the effect of the dispersed nanoparticles over the nanocolloïd properties, specially the ones related to ferroelectricity. This study showed no change over mesomorphic and ferroelectric behavior of the materials. A decrease in spontaneous polarization and phase transition temperatures was found for low nanoparticle concentrations. A "transition" of these behaviors was observed for a critical concentration, beyond which, nanoparticles aggregate and form clusters inside the liquid crystal matrix. Afterwards, we have studied two dielectric relaxation modes. The first one related to distorsions of the helix in the ferroelectric phase and the second one to the compression movements of the smectic layers around the ferroelectric-paralectric transition. The observed behaviors seem to be due to modifications of the visco-elastic properties of nanocolloids, produced by intercalation of nanoparticles between the smectic layers

Texte intégralAs part of its studies on detonation, the CEA at Gramat is interested in the dispersion of liquids in air, with high speed/energy constraints and multi-scale aspects. Measuring the particle size of the dispersed liquid is attracting a great deal of interest, but is proving complex because no commercial solution can be used under these particular conditions. However, under these conditions and given the impossibility of using laser sources in a pyrotechnic environment, no commercial solution is available. For this thesis, a new granulometry identification method was developed, based on a measurement known as "extinction", which is particularly easy to deploy and robust in harsh environments. This is a multispectral approach (measurement with cameras or a spectrometer) using a regularised inversion method in the sense of Tikhonov, based on the measure of spectral transmissions and which makes it possible to reconstruct the granulometry of the latter a posteriori using the Beer-Lambert law combined with the Mie model. Given the complexity of the phenomena involved in using explosives for dispersion, the method developed was tested on liquid dispersions reproduced on a small scale on sprays. The general method was developed by exploiting spectral information from controlled water sprays confined in an enclosure placed in a Fourier transform infrared spectrometer (high resolution). However, as this equipment is poorly suited to field conditions, the measurement method was downgraded by using cameras that allow "low resolution" but faster measurements. The use of an infrared camera operating in the 2-5 µm spectral band with spectral filters and a flat black body was therefore tested to monitor changes in spray particle size as a function of time. This method was subsequently applied to water dispersions using explosives, with promising results. The complete measurement and analysis process was therefore validated at each stage of the study
