TRANSDISCIPLINARY ACTIVTIES

Activity leaders

The department’s transdisciplinary activities are led by faculty members who are both teachers and researchers.

Context

The investigations of the THERMIE and SHARPAC teams rely on three transdisciplinary focus areas of research, allowing them to share their different skills and thus to optimize the progress in their scientific projects.


Goals and Research Areas

These three transdisciplinary focus areas are organized as follows:

› Systemic optimization : the objective is to propose methods of sizing and design by using the optimization of criteria characterizing the entire performance of the system under consideration. The goal is to better take into account, in studies of sizing and design, the interactions between the components of a single system (electric machines, heat engines, static converters, controls, electrochemical sources, mechanical transmissions, mission profiles, energy, fluidics, etc.) and to enable a more integrated design, efficient and adapted to the context of use and to the immediate environment.

These methods may be based on the implementation of the “rapid” analytical models or finite elements, more precise but “slower”, that characterize the different components to be connected in a single process of overall optimization, based on results already obtained in previous studies (NEXTER partnership: optimal design of a heavy hybrid electric truck; ALSTHOM partnerships: design of permanent magnet synchronous motors for rail transport).

› Magnetocaloric devices : the major scientific stake here is to understand alternating liquid flows under a magnetic field and temperature gradient so as to produce more efficient refrigeration systems (30% electricity efficiency targeted) and without the use of refrigerant fluids.

Two lines of development emerge:
- Multiphysics models;
- Metrology of magnetocaloric devices.

These magnetocaloric device investigations are conducted in connection with research done in the “Systemic optimization” area and with the SHARPAC team’s “Electric Actuators”.

› Micro-cogeneration : the main objective in this subject area is to design and characterize optimized electric/thermal cogeneration devices enabling production of useful electric energy and heat from external heat engines (Stirling Ericsson).

The overall modeling (semi)-analytic/analytic, digital and/or hybrid electric machines and external heat is also one of the objectives in this area.

These investigations are pursued notably in collaboration with the THERMIE team’s work on “Heat engines” and the SHARPAC team’s work on “Electronic actuators”.

The energy mix integrating different solutions of cogeneration including fuel cells may also be induced to develop further through these activities.
