Pauthenet, Martin. « Macroscopic model and numerical simulation of elastic canopy flows ». Thesis, Toulouse, INPT, 2018. http://www.theses.fr/2018INPT0072/document.
Texte intégralWe study the turbulent flow of a fluid over a canopy, that we model as a deformable porous medium. This porous medium is more precisely a carpet of fibres that bend under the hydrodynamic load, hence initiating a fluid-structure coupling at the scale of a fibre's height (honami). The objective of the thesis is to develop a macroscopic model of this fluid-structure interaction in order to perform numerical simulations of this process. The volume averaging method is implemented to describe the large scales of the flow and their interaction with the deformable porous medium. An hybrid approach is followed due to the non-local nature of the solid phase; While the large scales of the flow are described within an Eulerian frame by applying the method of volume averaging, a Lagrangian approach is proposed to describe the ensemble of fibres. The interface between the free-flow and the porous medium is handle with a One-Domain- Approach, which we justify with the theoretical development of a mass- and momentum- balance at the fluid/porous interface. This hybrid model is then implemented in a parallel code written in C$++$, based on a fluid- solver available from the \openfoam CFD toolbox. Some preliminary results show the ability of this approach to simulate a honami within a reasonable computational cost. Prior to implementing a macroscopic model, insight into the small-scale is required. Two specific aspects of the small-scale are therefore studied in details; The first development deals with the inertial deviation from Darcy's law. A geometrical parameter is proposed to describe the effect of inertia on Darcy's law, depending on the shape of the microstructure of the porous medium. This topological parameter is shown to efficiently characterize inertia effects on a diversity of tested microstructures. An asymptotic filtration law is then derived from the closure problem arising from the volume averaging method, proposing a new framework to understand the relationship between the effect of inertia on the macroscopic fluid-solid force and the topology of the microstructure of the porous medium. A second research axis is then investigated. As we deal with a deformable porous medium, we study the effect of the pore-scale fluid-structure interaction on the filtration law as the flow within the pores is unsteady, inducing time-dependent fluidstresses on the solid- phase. For that purpose, we implement pore-scale numerical simulations of unsteady flows within deformable pores, focusing for this preliminary study on a model porous medium. Owing to the large displacements of the solid phase, an immersed boundary approach is implemented. Two different numerical methods are compared to apply the no-slip condition at the fluid-solid interface: a diffuse interface approach and a sharp interface approach. The objective is to find the proper method to afford acceptable computational time and a good reliability of the results. The comparison allows a cross-validation of the numerical results, as the two methods compare well for our cases. This numerical campaign shows that the pore-scale deformation has a significant impact on the pressure drop at the macroscopic scale. Some fundamental issues are then discussed, such as the size of a representative computational domain or the form of macroscopic equations to describe the momentum transport within a soft deformable porous medium

Texte intégralThe aim of thesis is to present some macroscopic models for supply chains and networks able to reproduce the goods dynamics, successively to show, via simulations, some phenomena appearing in planning and managing such systems and, nally, to deal with optimization problems. Depending on the observation scale supply networks modeling is charac- terized by di¤erent mathematical approaches: discrete event simulations and continuous models. Since discrete event models (Daganzo 2003) are based on considerations of individual parts, their main drawback is, however, an enor- mous computational e¤ort. Then a cost-e¤ective alternative to them is continu- ous models, described by some partial di¤erential equation. The rst proposed continuous models date back to the early 60 s and started with the work of Baumol (1970) and Forrester (1964), but the most signi cant in this direction was Daganzo (1997), where the authors, via a limit procedure on the number of parts and suppliers, have obtained a conservation law (Armbruster-Marthaler- Ringhofer 2004, Dafermos 1999), whose ux involves either the parts density or the maximal productive capacity. Then, in recent years continuous and homogenous product ow models have been introduced and they have been built in close connection to other transport problems like vehicular tra¢ c ow and queuing theory. Extensions on networks have been also treated. In this work, starting by the historical model of Armbruster - Degond - Ringhofer, we have compared two di¤erent macroscopic models, i.e. the Klar model, based on a di¤erential partial equation for density and an ordinary dif- ferential equation to capture the evolution of queues, and a continuum-discrete model, formed by a conservation law for the density and an evolution equa- tion for processing rate. Both the models can be applied for supply chains and networks. Moreover, an optimization problem of sequential supply chains modeled by the Klar approach has been treated. The aim is to nd the con guration of pro- duction according to the supply demand minimizing the queues length, i.e. the costs of inventory, and obtaining an expected pre-assigned out ow. The control problem is solved introducing and minimizing a cost functional which takes into account the nal ux of production and the queues representing the stores. The functional is not linear, so to nd its minimum, the vectors tangent method is introduced. This technique is based on the choice of an input ow which is a piecewise constant function, with a nite number of discontinuities. Considering on each of them an in nitesimal displacement which generates traveling tempo- ral shifts on processors and shifts on queues, we are able to compute numerically the value of the variation of functional respect to each discontinuities. Finally, we use the steepest-descent algorithm to nd, via simulations, the optimal con- guration of input ow, according to the pre- xed desired production. [edited by the author]

Texte intégralCongestion in traffic networks is a common issue in big cities and has considerable economic and environmental impacts. Traffic policies and real-time network management can reduce congestion using prediction of dynamical modeling. Initially, researchers studied traffic flow on a single road and then, they extended it to a network of roads. However, large-scale networks present challenges in terms of computation time and parameters' calibration. This led the researchers to focus on aggregated models and to look for a good balance between accuracy and practicality.One of the approaches describes traffic evolution with a continuous partial differential equation on a 2D-plane. Vehicles are represented by a two-dimensional density and their propagation is described by the flow direction. The thesis aims to develop these models and devises methods for their calibration and their validation. The contributions follow three extensions of the model.First, a simple model in two-dimensional space to describe a homogeneous network with a preferred direction of flow propagation is considered. A homogeneous network has the same speed limits and a similar concentration of roads everywhere. A method for validation using GPS probes from microsimulation is provided. Then, a space-dependent extension to describe a heterogeneous network with a preferred direction of flow propagation is presented. A heterogeneous network has different speed limits and a variable concentration of roads. Such networks are of interest because they can show how bottleneck affects traffic dynamics. Finally, the case of multiple directions of flow is considered using multiple layers of density, each layer representing a different flow direction. Due to the interaction between layers, these models are not always hyperbolic which can impact their stability
