From PDEs to certified computational models : this is the motto of CARDAMOM . We aim at providing a robust model development methodology, as well as a quantitative approach to model certication, allowing to assess the robustness of the model w.r.t. each of its components (equations, numerical methods, etc), and to assess the variability of the outputs w.r.t. random variations of the data.
We will achieve this objective working toward a unified set of tools for the engineering analysis of complex flows involving moving fronts. Examples of such flows be found in civil, industrial, and aerospace engineering : industrial hazards (explosions), free surface hydraulics (coastal hydrodynamics, floods, etc), energy conversion facilities (gas-vapour, liquid-vapour systems, wave energy conversion, etc.), space-reentry (chemically reacting fronts, ablating walls, rarefied/continuous flows), wing de anti-icing systems (ice-air flow), etc.
Simulating, optimising, and controlling these systems in a robust manner is far from being a simple task, especially in a real life. There is still a large number of open scientic challenges. These are related to the intrinsic nature of these flows necessitating:
To develop a robust and accurate model means to be able to quantify and control the effects of the choices made in each of the above steps. The development of robust models taylored to the applications mentione above is the objective of CARDAMOM.Context
In this project, we aim to develop a shallow water model interacting with floating body structures. The objective is to develop a numerical tool capable of simulating the flows around complex energy converters in order to estimate their productivity in a real context and to optimize them.Assignment
Assignments : Up to now, the fluid/structure interactions are treated in the case of stationnary structures 1. The post-doctoral fellow will be in charge of the coupling of the strategy with the solid body dynamic sofware Chrono 2. A particular attention will be taken to the energy estimate of the numerical resolution. In a second time, high order strategy will be considered. In particular, the description of the shape of the floating object requires improved methods to preserve the order of the scheme, as the embedded boudary methods 3.
