The deployment of Hydrogen, as a solution to the energy transition problem, has received intense support in the recent years. If produced with renewable or nuclear energy, or fossil fuels using carbon capture, Hydrogen can help to decarbonize a large range of sectors, including transport and chemicals, where reducing emissions has proven to be particularly difficult. Hydrogen can also provide a support for the integration of variable renewables in the electricity system, being one of the few options for storing energy over long periods.
The widespread use of hydrogen in our society faces a major problem: the accidental hydrogen leaks and the associated risks of fire and explosion. These scenarios can have tragic consequences with a deep social impact that can slow down or even halt the deployment of hydrogen. To deal with this risk, it is essential to put in place effective mitigation measures, a point of vital importance for the entire hydrogen sector.
This internship proposes to study numerically the impact of a cloud of particles (liquid or solid) on the ‘reactivity’ of a hydrogen flame. The configuration to be studied is illustrated below. Particular attention will be paid to the mechanisms controlling the interaction between a cloud of particles and the flame with a focus on aerodynamic effects. On the long run, the study can be extended to include the thermal and chemical impact of these particles on the internal flame structure.
This internship will be co-supervised by CERFACS and Institut de Mécanique des Fluides de Toulouse (IMFT). An application for PhD program funding is currently underway. If the application is successful, the trainee will be able to pursue a PhD if he/she demonstrates good motivation.
During the internship, the student will develop a detailed understanding of the fundamental processes controlling the interaction of a hydrogen flame with liquid/solid particles, of major importance in a society marked by the rapid deployment of hydrogen-based solutions to the energy crisis.
The student will develop skills in numerical simulations using the DIVA code, developed at the IMFT, a reference for the simulation of multiphase flows.
