To maintain its technological lead, EPSILON carries out numerous resourcing projects. They are divided into three strategic axes:
- Multi-physical modelling of complex phenomena
- Data-Sciences and Scientific Informatics
This strategy stems from a simple analysis: Physical systems and phenomena are increasingly complex and costly to design. Simulation can make it possible to speed up the design of new products by making it possible to avoid long and laborious test phases. Modern modelling and simulation methods make it possible to evaluate physical properties but also the behaviour of complete systems (simulation of a satellite, simulation of an aircraft engine, a battery, a furnace, etc.), this is axis 1.
From time to time, the complexity of the systems studied requires the use of intensive calculations or scientific computing. In other cases, there are too many parameters for a physical approach, so statistical methods have to be deployed to analyse the data and establish correlations, this is the field of Data-science, axis 2.
Finally, when modelling and simulations have made it possible to make progress, it is necessary to validate this through tests or validation experiments, hence our axis 3, metrology.
Each of these axes is necessary to constitute a coherent approach to our research strategy. The details of the different actions are described in the attached appendices.
Axis 1 : Multiphysics modelling
In the field of multi-physics, EPSILON concentrates its R&D activity on 3D modelling to carry out one-off studies and 0D, 1D for system studies.
Studies have been carried out on the following themes:
- 3D Modelling
- Thermal and Fluid Coupling
- Thermal and Mechanical Coupling
- Thermal and Electromagnetic Coupling
- 0D, 1D Modelling
The sectors studied concern space, industrial installations (buildings), aeronautics, energy and finally the automobile industry.
Axis 2: Scientific computing - Data-Sciences
In the field of scientific computing, our work has concerned the development of software for post-processing massive and heterogeneous data to establish and visualize correlations using several approaches (physics, statistics, semantic analysis).
Our 2019 R&D effort made it possible to finalize a version of the software called T2P for post-processing data related to thermal simulations. Several feasibility studies on statistical (ADEME) or semantic (CNRS) analyses were also carried out, with a general observation: the quality of input data is a fundamental parameter that is neglected and poses enormous technical difficulties.
Axis 3: Metrology
In the field of metrology, our work has focused on feasibility studies on several methods of measurement and physico-chemical characterization of materials down to the component. Several themes have been developed:
- Thermal Metrology
- Measurement of heat flow
- NDT using Infra-Red thermography
- Fluidic and Mechanical Metrology
- Movement measurement
- Fluidic measurement and management
EPSILON and its Collaborative Projects
Preparing for the future is at the heart of the values of EPSILON and more generally of the ALCEN group and is expressed by the importance it attaches to scientific resourcing projects either through its own research projects or through collaborative projects .
This strategic choice is characterized by very strong collaboration with public research organizations, universities and certain manufacturers (system integrators, equipment manufacturers and component founders) both at French and European level.
This resourcing respects a road-map updated annually and are deployed by a set of projects including:
- GENOME (Optimized Energy Management) which deals with the substitution of electric for hydraulic in aeronautical applications,
- e-TAG which deals with the micro-hybridization of a gas turbine to recover thermal energy in a helicopter engine system,
- EDYPHICE dedicated to the optimization of heat exchanges by Electro-Hydro-Dynamic (EHD) effect.,
- CANOPEE which aims to design and test a prototype cooling solution by active pumping of a fluid,
- ATHERMO dedicated to the miniaturization of a broad spectrum thermal non-destructive control technology,
- MONOLIT dedicated to the optimization of a solar energy, battery and lighting system,
- SOCOOL dedicated to new cooling technologies for aeronautical systems and subsystems.
EPSILON is also a founding member of the Board of Directors, the Labelling Committee and the Executive Committee of the AEROSPACE VALLEY division.
