Hermange, Corentin. « Simulation des interactions fluide-structure dans le problème de l’aquaplaning ». Thesis, Ecole centrale de Nantes, 2017. http://www.theses.fr/2017ECDN0014/document.
Texte intégralThe aquaplaning problem has been the topic of simulation works emphasizing its complexity: fluid structure interactions, structures modelling, materials involved, contact with asphalt and the complexity of the resulting fluid flow (extremely complex interface, drying up the road, ventilation, possible development of turbulence and cavitation). As additional difficulty, the tire is a highly deformable body and fluid-structure interaction effects should be considered, leading to a challenging problem for the numerical modelling. Then Michelin, Ecole Centrale Nantes and NextFlow Software have recently tested the ability of the SPH solver developed by the two latter to classify tires based on their surface structure geometries, without considering the gas phase. In this context, the interest of SPH for modelling efficiently the aquaplaning flow has been underlined. The meshless and Lagrangian feature of SPH naturally avoid the problem of fluid/solid grid compatibility. The other significant advantage of the SPH method, in this context, appears in its ability to be relatively easily coupled to with conventional Finite Element solvers. The aim of this workis three fold. First, qualify the SPH-FE coupling strategy, especially in terms of energy and then develop schemes to ensure a good compromise among stability, accuracy and computation time. Second, quantify the influence of different involved physical phenomena to determine which should be modelled. Finally, adapt SPH models to simultaneously consider different phenomena and to performe simulations of the complete problem

Texte intégralA method to couple smoothed particle hydrodynamics and finite elements methods for nonlinear transient fluid–structure interaction simulations by adopting different time-steps depending on the fluid or solid sub-domains is proposed. These developments were motivated by the need to simulate highly non-linear and sudden phenomena that take into acount solid impacts and hence require the use of explicit time integrators on both sub-domains (explicit Newmark for the solid and Runge–Kutta 2 for the fluid). However, due to critical time-step required for the stability of the explicit time integrators in, it becomes important to be able to integrate each sub-domain with a different time-step while respecting the features that a previously developed mono time-step coupling algorithm offered. For this matter, a dual-Schur decomposition method originally proposed for structural dynamics was considered, allowing to couple time integrators of the Newmark family with different time-steps with the use of Lagrange multipliers

Texte intégralThe wet grip performance of tires is an essential criterion affecting the safety of passengers. In this situation, the tire/ground contact becomes more complex to understand and model, involving non-trivial physical mechanisms such as fluid-structure coupling and turbulent flows. In the vision of improving our understanding of tires’ hydroplaning, this thesis aims to set up a comparison strategy between the SPH-Finite Elements coupled numerical simulations and the r-PIV testresults. Indeed, the SPH method has many advantages due to its Lagrangian and meshless nature to model the fluid part. Moreover, its coupling with the finite element method is relatively easy. In addition, the r-PIV was recently introduced for experimental investigations of a tire rolling over a water puddle. This new approach performed effectively as a powerfultool for validating numerical simulations based on local comparisons of the water circulation for a given tire tread. Finally, numerical simulations also evaluate r-PIV thanks to a 3D vision of the phenomenon and access to data that are still inaccessible experimentally
