Bancora, Simone. "Characterization of fabric layups by pressure print analysis and simulation of dual-scale flow based on topological skeletonization : application to composite materials processing." Thesis, Ecole centrale de Nantes, 2021. http://www.theses.fr/2021ECDN0049.
In this work, we study continuous fiber preforms in the context of Resin Transfer Moulding (RTM) processes. The aim of the thesis is two-fold: propose a new methodology to obtain mesoscale geometrical data from preforms and provide a new numerical model able to predict permeability or perform mesoscale filling simulations in a computationally efficient way. In the first part, the focus is on the acquisition of geometrical data from preforms: we propose a novel methodology based on the analysis of the pressure field experienced by a dry preform under compaction. By using a commercial pressure-sensitive film, the pressure field exerted by a stack of layers against mould walls is captured and analyzed. Taking advantage of the periodic morphology of textiles, geometric patterns revealed by the pressure field are interpreted according to spectral Moiré analysis to recover the orientation and spatial distribution of each individual layer in the stack. In the second part, the reconstructed digital architecture of the preform is used to carry out numerical flow simulations at the scale of the yarns, to characterize permeability of the stack or directly perform filling simulations. The stack geometry is replaced by a skeletonized representation of the same, on which a two-dimensional flow problem can be solved numerically, greatly reducing the computational cost when compared to a full 3D approach. This “medial skeleton” model is first formulated in its single-scale version (flow in channels) and then extended to dual-scale (flow in channels and yarns). The model potential is illustrated through several test cases. This research establishes a pathway going from the non-destructive acquisition of data to the simulation of the dual-scale flow inside a multi-layer layup of textiles

Neurovascular coupling (NVC) has become the key aspect for understanding brain function. A multimodal exploration would aim to identify the early NVC biomarkers and determine their predictive character. Paper (1): In this chapter, the photothermal interaction of NIR laser on human tissues were modelled in silico. The results demonstrated the safety of the noninvasive optical evaluation of the brain function and the maximum temperature increase was higher in the neonatal brain than in the adult brain. Paper (2 & 3): The main purpose of this thesis was to provide a multimodal view of the NVC and cerebrovascular regulation in the neonatal premature brain. Paper (2): Key findings included that rCBV and rCMRO2 have a predominant driving influence on rCBF at the resting-state in the preterm neonatal brain. Paper (3): The bursts of electroencephalographic activity in neonates in resting state were found to be coupled to a transient hemodynamic response involving different types of hemodynamic response including: (a) positive stereotyped hemodynamic responses (increases in HbO, decreases in HbR together with increases in CBF and CMRO2), (b) negative hemodynamic responses (increases in HbR, decreases in HbO together with decreases in CBF and CMRO2), (c) Increases and decreases in both HbO-HbR and CMRO2 together with no changes in CBF. The establishment of neurovascular coupling system was observed as a function of age. High coherence was observed between the cerebral hemodynamic (vascular) and electrical (neuronal) oscillations which was less in the non-encephalopathic newborns than in the two pathological groups

The aim of this work was to improve high-risk hypertensive care with cardiovascular outcomes especially metabolic syndrome. Blood pressure (BP) parameters and pulse wave velocity (PWV) were detected using non invasive technics. The first step consisted in analyzing the fiability of the oscillometric BP measurements in obeses with a large arm. As a second step, the effect of clinical or ambulatory BP, heart rate, and metabolic syndrome factors on arterial stiffness assessed by PWV was evaluated by conducting phase IV studies. Finally, we evaluated the BP normalization values after a short to medium term treatment of hypertensive diabetes and non diabetes with different antihypertensives (ARB : angiotensin 2 receptor blockers, ACEI : angiotensin converting enzyme inhibitors, and CCB : calcium channel blockers)

In this project, a new architecture of an air-driven micropump prototype with self-actuating microvalves is presented. A finite element model is also presented. Fabrication and characterization of the system and the electronic control of the micro-pump was also introduced. The designed micropump was able to generate a flow rate of 9 µL/min. Pumping pressure was 1500 Pa. Frequency of membrane deformation was 1.25 Hz and its maximum deformation was 3.66 µm. Finite element modeling shows that the flow rate ratio between the admission and delivery phase was 99.99 %. Fabrication of the micropump was achieved through two processes. First, a manual molding for microvalves with cylindrical and cubic chambers whose external dimensions was 8 mm x 12 mm x 6 mm and actuation membrane thickness of 20 µm. The entire system, including the membrane, was made from polydimethylsiloxane (PDMS). Second, in collaboration with the department of mechanical engineering, a new printing process based on sugar glass was also used. The latter is based on the 3D printing of a sugar mold. The mold is dissolved after the pouring and curing of PDMS. The actuating chambers of the micropump wetre cylindrical with a diameter of 4 mm and a height of 1 mm. The pumping chamber was also cylindrical with the same diameter but with a height of 0.5 mm. The thickness of the pumping membranes was 250 µm. Through this process, the entire pumping system (expect microvalves) were fabricated as a one block to eliminate leakage and reduce system dimensions. The external dimensions of the micropump was 20 mm x 20 mm x 10 mm. Experimental results of the micro-pump showed that the flow rate that can be generated is 7 µL/min. The electrical power consumption of the system was 114 mW. Finally, the microvalve can resist to a back pressure up to 13 psi. A graphical interface to control the actuation part of the micropump using an FPGA has also been developed.
