Description

JOB ENVIRONMENT:


  • Institut Mines-Télécom_ is the leading public group of engineering and management _Grandes Écoles_ in France. Consisting of eight public graduate _Grandes Écoles_ and two subsidiary graduate schools, _Institut Mines-Télécom_ leads and develops a rich ecosystem of partner schools, economic, academic and institutional partners, key players in education, research and economic development.


Mines Saint-Étienne, a graduate school of the _Institut Mines-Télécom_, is responsible for education, research, innovation, industrial transfer and scientific culture dissemination.

With 2,500 students, 500 staff and a budget of €50m, it has 3 campuses dedicated to the industry of the future, health and well-being, and digital sovereignty and microelectronics.

It is ranked in the top 15 graduate engineering schools in France and the top 500 universities worldwide.

The strategy of Mines Saint-Etienne is in line with that of _Institut Mines Telecom_


It aims to:

  • Support the ecological, digital and generational transitions and educate the people involved
  • Support national and European sovereignty in microelectronics and digital technolog
To support this strategy, it is recruiting a
postdocoral.


JOB DESCRIPTION:


HYGEN is a ADEME funded project spearheaded by FIVES CRYO, a leading company in the manufacturing of cryogenic heat exchangers.

It aims at developing and improving the process of hydrogen liquefaction which is a key step towards its storage and handling on an industrial scale.

Indeed, the target is a 100-fold increase of the liquefaction capacities.


In this context, SPIN, which is the chemical engineering research center of Mines Saint-Etienne is in charge of improving the filling process of the heat exchanger with granular catalyst particles.

The present job offer is a 18 month post-doctoral contract which will take place in the laboratory of Mines Saint

  • Etienne.


The main barrier of this project is the very confined space between the exchanger plates which prevents an easy and homogeneous filling.

The study will be focused on the use of vibrations to improve the filling procedure.

In this context, the project aim at (i) contribute to the understanding of particles flow in confined space (ii) eval
- uate the capability of vibrations to improve the flowability and analyse the mechanism involved and (iii) improve the vibrations cycle.

  • The first one is about ~10 cm of height and width and will be used to visualize the particle packing by means of 3D
  • X rays microtomomography. The analysis of tomography images should allow us to eval
- uate different parameters related to the particle packing and its homogeneity.

  • The second one is also ~10cm width but higher (~70cm). It will be used to evaluate the residence time distribution of gas. To do so, a neutral gaseous will be injected (Argon) until the setup is filled and then a short inflow of Nitrogen will be sent. Finally, the concentration of nitrogen in the outflow will be measured. This measurement should allow us to identify flow paths.


Then, for each experimental setup, parametric study will be led to analyse the effect of vibrations on the particles flow in this very confined geometry.

The variable parameters might concern both process and powders:


  • Acceleration and amplitude of the vibrations
  • Geometry of the heat exchanger's Fins
  • Particle size distribution and powder morphology
The position is based on the Saint-Étienne campus and Hygen partners collaborations (CEA, FIves Cryo) are encouraged.
