Dallagi, Heni. "Numerical and experimental investigations of the rheological behavior of foam flow : application to the cleaning of surfaces contaminated by microorganisms in the food industries". Electronic Thesis or Diss., Université de Lille (2022-....), 2022. http://www.theses.fr/2022ULILR003.
In this research, experimental and numerical characterization of the rheological behavior of an aqueous foam flowing inside a horizontal pipe with and without singularities (presence of half-sudden expansion, and a fence) were investigated. Different conditions of foam flow were studied by varying the foam qualities (from 55% to 85%), and three Reynolds numbers (32, 65, and 97). Measurements of the pressure measurements, and at the wall the local velocity repartition and the thickness of the liquid films using respectively pressure sensors, Particle Image Velocimetry, and a conductimetry technique shown a reorganization of the foam downstream the geometry change, with a thicker liquid film at the duct bottom, larger bubble sizes at the top, as well as a larger foam void fraction increased from the bottom to the top part of the duct section. In addition, foam would present a visco-elastic character comparable to a non-Newtonian monophasic liquid. Computational Fluid Dynamics simulations were undertaken to predict this rheological behavior of the foam, the two models Herschel-Bulkley and Bingham were tested taken into account the presence of an underlying liquid film at the bottom of the channel . Comparison between experimental and numerical results showed that regardless of the foam quality, Herschel-Bulkley model could accurately describe the rheological behaviour of the aqueous foam under the different flow conditions analysed.The second target was to investigate the ability of a wet foam flow (quality of 50%) to clean stainless-steel surfaces contaminated by microorganisms. For this purpose, two different contamination patterns were studied, droplets containing Bacillus subtilis spores (either hydrophilic Bs PY79 or hydrophobic Bs PY79 spsA), and biofilms produced by three bacteria strains encountered in food industry production plants (Escherichia coli SS2, Bacillus cereus 98/4, and Pseudomonas fluorescens Pf1). Different flow conditions were performed by varying the wall shear stresses (2.2 - 13.2 Pa), and bubble sizes (0.18-0.34 mm) in a straight duct with no geometrical changes, in order to identify the mechanisms of contamination release and thus better control and optimize the foam cleaning process. Results show that compared to conventional cleaning-in-place, foam flow effectively removed Bs spores as well as Bc-98/4, Ec-SS2, and Pf1 biofilms. Moreover, the combination of high shear stress at the wall and small bubble sizes (<0.2 mm) showed promise for improving the cleaning efficiency of spores. On the other hand, a clear improvement of the biofilm removal was observed when increasing the mean wall shear stress. The characterization of the foam and the interface phenomenons (using polarography, conductimetry, and bubble size analysis methods) indicated that mechanisms such as fluctuation in local wall shear stresses, or in the liquid film thickness between the bubbles and the steel wall induced by bubble passage, foam imbibition, and sweeping of the contamination within the liquid film could participate largely to the removal mechanisms. Finally, the life cycle assessment study demonstrated that foam flow cleaning could be a suitable technique to reduce water and energy consumption (7 and 8 times less, respectively) presenting less environmental impacts than CIP processes, with about 70%. Lastly, foam flow cleaning can be an alternative method, which can improve efficiency and reduce environmental impact. Additional activities conducted during the PhD period related to hygienic design are presented highlighting the role of the contaminants (spores and biofilms), the material (other than stainless steel) and the geometry (ducts or more complex design) in hygiene monitoring

Surface patterning and epitaxial regrowth are key technologies for novel optoelectronic (nano) devices. The aim of this thesis has been to develop a preparation of GaAs micro- and nanopatterned surfaces suited for regrowth and to study the organization of InAs quantum dots on these surfaces. The patterns have been achieved by electronic lithography in a cap resist and transferred into GaAs by chemical etching. Surface decontamination by a O2: SF6 micro-wave plasma has been demonstrated. Roughening upon in situ deoxidization has been prevented thanks to a low temperature H plasma treatment. Molecular beam epitaxy on these patterned surfaces has been studied. InAs quantum dots have been grown and lateral ordering has been attained. This preparation method has been shown to be efficient for GaAs selective regrowth on Si3N4/GaAs patterned surfaces

In microelectronics, the course of miniuaturization imposes the introduction of metal and dielectrics layers in CMOS transistors to improve electrical yields. However, this integration involves a total review of process (thermal treatment, etch, wet steps. . . ). This work particularly focus on Front End cleans steps around the gate. Challenges are following : first, there must remove more and more all types of contamination with minimum materials consumption and without damages on sensitive structures. On the other hand, the process must be chemical compatibility with new materials. There also must be integrated in a new configuration tool (single wafer instead of batch tool). Thus, they must be involved to give best performances. It's why, today, provide an Advanced clean process for CMOS sub-45nm technology node is a real challenge
