Developing visualisation strategies for ultrafast optics Performance-oriented coding: extension of a C++ code, C/Python API

1/ Massively parallel numerical analysis of the breakup process in a small-scale gasifier with the SPH (Smoothed Particle Hydrodynamics) method 2/ Experiments on primary breakup for academical studies and industrial partnerships (Shadowgraphy, LDA/PDA, Laser diffraction) 3/ Lecturer: “Thermal Turbomachinery” for Master students for 3 years, 3 hours/week. 4/ Supervision of 21 students (for Bachelor and Master thesis). One received the Wolfgang Heilmann Price (DGLR/MTU) for outstanding Master Thesis.

In the context of fuel injectors for aeroengines, I developed a film and an atomization model (PAMELA). Thanks to PAMELA, it is possible to predict the drop size distribution of the fuel spray in the combustion chamber, and to predict the combustion regimes. I implemented these models in AVBP (the HPC reactive CFD code of CERFACS-IFPEN), and applied them to a helicopter combustion chamber. Since then, PAMELA is regularly used in AVBP for academic research, and in the industry (SAFRAN, Rolls Royce)

I was responsible for conducting the tutorials about ‘Mathematical Tools for Engineers’. This activity included small courses, exercises and a small project with Matlab. The topic were Theory of Distributions, Fourier/Laplace Transforms, Partial Differential Equation.

I was responsible for supervising the practical experiments on linear elasticity and for correcting the reports

As a CFD Engineer, I completed several missions at the Arcelor-Mittal research center (Bars & Wires, Maizières, France) in the field of Thermal Exchanges and Cooling (Phase-change cooling, Effusion cooling). I also developed several model to predict temperature and to control on-line cooling devices (FORTRAN, C++, Delphi) As a software developer for Valeo, I developed new functionalities in in-house software controlling the production line and communicating with the logistics (PCSDP)
