At the CNRS, in the laboratory ICARE (UPR3021) located on the CNRS campus in Orléans, the candidate will be responsible for developing a numerical code for the simulation of nanoparticle formation as part of an European project, FUN-PM, led by A. Comandini. The work will focus on the improvement of a code which has been developed at ICARE for the simulation of the solid-phase chemistry in shock tube experiments (0-D system). In particular, the different steps involved in the particle formation, from nucleation to chemical growth and coagulation, from agglomeration to oxidation, will need to be updated or added to the code based on the recent discoveries in the field. The nanoparticle code will be finally coupled to a gas-phase kinetic model and used to simulate experimental data obtained with shock tube experiments on different fuel components and mixtures. The gas-phase kinetic model and the experimental work are the subject of two ongoing theses. The nanoparticle code will be for use in engine and turbine CFD codes to implement cleaner designs and solutions.
The research project has several components:
- analyze the different mathematical models proposed in the literature to describe the nanoparticle solid-phase chemistry;
- include such models in the numerical code;
- couple the gas-phase and the solid-phase modules;
- validate the code against the shock tube experimental results.
The candidate will also supervise the experimental activities performed by a PhD student, he/she will be involved in writing journal articles and he/she will present the results at international conferences.
The candidate's profile must be in line with the description of the research project;
the candidate must have :
- PhD in mechanical/chemical engineering or equivalent with experience in numerical modeling;
- strong knowledge of numerical programming languages (Python, FORTRAN,…);
- basic knowledge of chemical kinetics and combustion preferred;
- ability to work in team on multi-disciplinary projects;
- good level in English;
- ability to write articles for international conferences and journals.
The CNRS ICARE laboratory in Orléans has about 100 people, including 33 researchers and teaching researchers. The candidate will work in the Shock Wave team and more specifically in the framework of the research program, FUN-PM, funded by the European Commission (ERC Starting Grant) which started in February 2018 with the aim of clarifying the complex processes that lead to the formation of primary structures. Indeed, the chemistry associated with the formation of nanoparticles from commercial fuels is still poorly understood, limiting our ability to improve the design of combustion devices.
