METHRIC-Projects and partnerships

FINE/Marine

Since 2006, a special valuation action has been carried out between Centrale Nantes, CNRS and NUMECA International around the FINE / Marine software. Applications have resulted from the use of this software, notably in the context of the last America's Cup and the 35th (challenges Oracle Team USA, Emirates Team New Zealand and Groupama Team France) The year 2013) or the Galactica Star (World Super Yacht Award 2014). This action is included in the "Top Ten" of CNRS valuation since 2012.
 

ORUP: Shape optimization using adaptive multi-fidelity metamodels - Carnot MERs project

To continue to increase the energy performance of ships and reduce their emissions, naval architects need reliable simulation tools to identify the best hull shapes. It is even becoming possible today to develop these optimal shapes in a fully automatic way. However, this research is very expensive in terms of computing time. The ORUP project aims to improve the robustness and efficiency of automatic procedures for finding optimal shapes.
The new process is applied to the optimization of hydrofoils. These underwater wings allow fast boats to be lifted entirely out of the water, thus reducing their energy consumption or increasing speed for sport sailing. The final objective of the project will be to demonstrate the ability to automatically search for the optimal shape of a realistic hydrofoil.

Closed-loop control of the wake of a road vehicle - COWAVE:

In this project, we propose robust drag and fuel reduction solutions for road-vehicles by closed-loop control of turbulent flows working efficiently for a range of operating conditions including changing oncoming velocity and transient side winds. To achieve this goal, we combine passive, active control and closed-loop strategies by using compliant deflectors, unsteady micro-jets and Machine Learning techniques. This project aims to prove a feasibility of the control from laboratory scale up to a full-scale industrial demonstrator. The main repercussions of the project will be on the reduction of the environmental impacts of transport industry and the gain of competitiveness and employment. Control strategies will be mainly developed by PPRIME Institute. Experiments will be done in PRISME and PPRIME. LHEEA will take in charge numerical simulations and optimization. Finally, PSA will provide the vision of an automobile manufacturer on the industrial feasibility of the developed control strategies."

International NATO-AVT Project:

The work of the working group of this collaborative international project under the aegis of the North Atlantic Treaty Organization (NATO) brings together leading aerodynamic and hydrodynamic research teams from member nations of the NATO and aims to evaluate the simulation capabilities of digital tools for the design of both airborne and land and sea vehicles. The acronym AVT stands for "Applied Vehicule Technology" and 13 institutes are involved in conducting measurements (EFD) and simulations (CFDs).
