Back to original languageAbout Mbaye
Mechanical-energetics engineer specializing in numerical simulation and fluid mechanics, I work on CFD, thermal, and HVAC issues. I have worked on thermo-fluid studies in demanding environments, particularly at Renault through Segula Technologies, where I developed models, analyzed complex physical phenomena, and produced clear and actionable technical reports.
I master modeling, numerical resolution, and result interpretation, with a rigorous and performance-oriented approach. I place particular importance on physical understanding, mesh quality, the relevance of turbulence models, and the communication of results.
I can be involved in simulation, analysis, optimization, technical popularization, or methodological support missions.
