Texte intégralNumerical simulation of turbulent aerodynamics flows remains challenging. Such fluid-structure interaction problem involves generally a thin layer close to the wall where the fluid is slow down, called boundary layer. This latter requires a carefull study of the boundary layer since it is crucial regarding the accuracyof the complete flow computation. Therefore, a fine and structured mesh is needed close to the wall. In this work, we propose a novel automatic procedure to build a correct boundary layer mesh according to the theory and the flow parameters. Moreover, in order to describe exactly the behaviour of the flow on the whole domain, the boundary layer mesh is combined with a dynamic mesh adaptation method.It follows an advanced version of the edge based mesh adaptation method. Combined together, they ensure a fine and structured mesh in the boundarylayer while all the flow vortices are accurately resolved. This new method, called boundary-volume mesh adaptation, has been validated on several 2D and 3Dtest cases with complex geometries. Results emphasises the capacity ofthe approach and offer opportunities of improvement for numerical fluid mechanics mesh adaptation
Bonaventure, Julien. « Influence of random surface roughness on friction in elastohydrodynamic, mixed and boundary lubrication ». Thesis, Lyon, 2017. http://www.theses.fr/2017LYSEC038/document.
Texte intégralMost mechanical systems include lubricated contacts submitted to important strengths. The present work deals with the influence of surface roughness on friction in the elastohydrodynamic (EHD), mixed and boundary lubrication regimes, with operating conditions that are typically those found in an internal combustion engine. Most of the surfaces used in the experiments are machined steel, with or with a Diamond-Like Carbon (DLC) coating. Given the friction in boundary and mixed lubrication being higher than in EHD lubrication, it is crucial to predict the transitions between these regimes. These strongly depend on surface roughness. There are very few experimental works that deal with this issue, and the theoretical attempts to include the influence of random surface roughness are based on roughness parameters that are difficult to measure because of their dependence towards the sampling conditions and their non-stationarity. Based on numerous topographical surveys (using interferometry and AFM), a method is implemented to ensure the representativeness of roughness statistical parameters in order to characterize a range of surface roughnesses within the interval [0.001 ; 1] μm. Then, these surfaces are rubbed against each other using Stribeck procedures in order to correlate their morphology to their friction behaviour. The high-pressure rheology of poly-α olefins is measured in smooth contacts with respect to the pressure and the temperature. This not only allows to quantify the friction force for any contact operating in EHD lubrication, but also to set a criterion to spot the onset of mixed lubrication. At high entrainment speed, the viscous shear stress vanishes, which is often attributed to shear heating. It is shown that thermal effects can not explain such a drop of friction for our own experiments. However, the widening of the pressure profile — which becomes significant when the film thickness becomes comparable to a tenth the contact length — is more likely to explain this behaviour. Our results show that the product of the inlet viscosity with the entrainment speed, spotted at the mixed-EHD transition, follows a super linear power law with the RMS roughness, whatever the materials involved, which allows to predict whether a contact operate in mixed lubrication or not. The transition from mixed to boundary lubrication reveals material and roughness-dependent with a clearly different behaviour between DLC/DLC contacts and contacts involving at least one steel body. Regarding the DLC/DLC contacts, the boundary friction is due to the plastic shearing of the lubricant, which explains why surface roughness has no influence on boundary friction for these contacts. With Steel/DLC and steel/steel contacts, the boundary friction presents two monotonous trends versus the composite RMS roughness. Eventually, a mixed bearing model based on the Greenwood-Willimason assumptions was implemented and allowed to reproduce quite closely the experimentally obtained Stribeck curves. This implementation indicates in particular the sampling conditions that are optimal to capture relevant asperity parameters
Blackman, Karin. « Interactions multi-échelles entre la basse atmosphère et la canopée urbaine ». Thesis, Ecole centrale de Nantes, 2017. http://www.theses.fr/2017ECDN0028.
Texte intégralThe urban boundary layer consists of complex coherent structures, such as large-scale low momentum regions and intermittent turbulent sweeps and ejections, which are responsible for the transport of heat, momentum and pollution. Although these structures have been well identified, their quantitative relationship with the flow inside the canopy is still unknown. Wind tunnel modelling of flow over simplified rough terrain consisting of either three-dimensional or twodimensional roughness elements are able to reproduce these structures and are used to investigate the nonlinear relationship between large-scale momentum regions and small-scales induced by the presence of the roughness. As the temporally resolved small-scale signalis not available Linear Stochastic Estimation is used to decompose the flow into large and small-scales and confirm that the large-scale structures within the overlying boundary layer influence the small-scales close to the roughness through a non-linear mechanism similar to amplitude modulation. Changing terrain configuration from 3D to 2D roughness results in a modification of the non-linear relationship closer to the shear layer that develops near the top of the obstacles. The full turbulent kinetic energy (TKE) budget including dissipation is calculated using an LE-PIV model and demonstrates that small-scale structures within the shear layer are important to the production, transport and dissipation of energy. Finally, triple decomposition of theTKE budget confirms that the non-linear relationship that exists between large-scale momentum regions and small-scales close to the roughness is related to energy transfer between these structures

Photographs taken at night time with haze often suffers from poor visibility and color distortion due to uneven local light sources. In this scenario, the common daytime dehazing algorithm results increased atmospheric light due to the influence of local light sources. Due to this, the result of the transmission is affected, resulting in excessive haze removal, noise amplification and artifacts introduction. Consequently, this thesis proposes a new night time dehazing algorithm by modifying the calculation method of atmospheric light and transmission used in the dark channel priors proposed by He[2]. First, the proposed erosion Gaussian-based dark channel is applied to suppress local light sources. Subsequently, a modified transmission calculation method is proposed which combines the erosion operator with the transmission. As the transmission is obtained, the refinement operation is performed. The multi-scale guided filter utilizing improved transmission is applied to the proposed multi-scale guided filters for refinement. Through this improved calculations, the unpleasant issues can be well controlled, including excessive dehazing, excessive darkness, artifacts and excessive amplification of noise. In addition to the above three improvements on the dehazing algorithm, the ICLAHE proposed by Guo[22] et al is also modified with multi-scale clipping limits to further improve the image quality. With the proposed Multi-scale clipping limit of ICLAHE, details can be obtained. As documented in the experimental results, the proposed method can yield superior performance towards nighttime dehazing effect and of less computational complexity in comparison against the state-of-the-art methods.
