Les missions du poste
The Postdoctoral Researcher will play a key role in the development and validation of the absorption injector, covering the full research cycle from physical modelling to experimental demonstration.
Your main tasks will include:
· Developing simplified 0D thermodynamic and hydrodynamic models for preliminary injector design and sensitivity analysis;
· Developing advanced multiphase and multi-species models and performing CFD simulations to investigate flow, mass, momentum and energy transfer within the injector;
· Contributing to the detailed design and manufacturing of injector prototypes;
· Adapting and operating an experimental test bench for the thermo-hydraulic characterisation of the injector;
· Conducting experimental campaigns and validating numerical models against experimental data;
· Analysing results and identifying opportunities for performance optimisation;
· Publishing research results in international journals and contributing to patent applications.
The project offers the opportunity to follow an innovative technology through the complete development process:
Physical modelling CFD simulation prototype development experimental validation scientific publications and technological innovation.
· Location: CEA LITEN - INES Site, Le Bourget-du-Lac, France
Le profil recherché
You should hold a PhD in Energy Engineering, Mechanical Engineering, Thermodynamics, Fluid Mechanics, Process Engineering, or a related field.
We are looking for a creative and enthusiastic researcher with a strong background in one or more of the following areas:
· Thermodynamics and energy systems;
· Multiphase flows and fluid mechanics;
· CFD and numerical modelling;
· Experimental thermal or fluid systems;
· Scientific programming and data analysis.
Experience with absorption systems, ammonia-water mixtures, injectors/ejectors or phase-change phenomena would be an advantage, but is not mandatory. You should be scientifically curious, proactive and able to work independently while enjoying collaboration in a multidisciplinary research environment. A good command of written and spoken English is essential.
Why Join Us?
This position offers a unique opportunity to work on an innovative and potentially disruptive energy technology addressing one of the major challenges of the energy transition: delivering sustainable cooling with significantly reduced electricity consumption.
You will join CEA LITEN, a leading European research institute dedicated to new energy technologies, and benefit from:
· Access to advanced numerical and experimental facilities;
· A stimulating and multidisciplinary research environment;
· Opportunities to publish in international scientific journals and present your work at major conferences;
· The possibility to contribute to technological innovation and patent development;
· The opportunity to build a strong scientific profile at the interface between fundamental research, numerical modelling and experimental technology development.
The project is expected to generate 2-3 scientific publications and contribute to 2-3 patent applications related to injector design, system architecture and control strategies.
