Chemical Looping Combustion (CLC) has emerged as an efficient oxy-combustion process for carbon dioxide capturing because CO2 is easily separated from the other flue gas components. Indeed, the process is composed of two reactors, where a solid metal (called oxygen carrier) is circulating between the reactors, transporting O2 from the Air Reactor (AR) to the Fuel Reactor (FR). The combustion, in the FR, is then conducted with pure oxygen yielding to high CO2 concentration enabling efficient carbon capture necessary to achieve the carbon neutrality.

The present internship leading to a PhD position, is part of an innovative French project to improve knowledge and skills in oxy-combustion. The consortium of eight academic partners gathers specialists around two approaches: chemical looping combustion (CLC) for biomass and oxyfuel flames for biogas. The project is based on the consortium’s recognized expertise in advanced diagnostics applied in oxy-combustion experimental facilities and high-performance numerical simulation to build refined databases and numerical modeling tools for the development of sober, high energy efficiency technologies applicable in an extensive range of applications: gas turbines, boilers, glass, steel, power, and cement plants.

In the above-mentioned project, a multi-scale approach is considered for the CLC simulation to model heterogenous reactions with soot formation in a two-phase gas-solid dense regime flow in the FR. The intern will initially extend the in-house code RESPECT-FUGU features, from homogenous and surface reactions to heterogeneous reactions in order to simulate the biomass pyrolysis and the char gasification present in the FR. Once these developments are validated, Particle-Resolved Direct Numerical Simulations are to be performed, using the code RESPECT-FUGU, to provide a very fine characterization of the reactive particulate flow typical of a fuel reactor and develop closure laws to be used at macroscopic scale.
