CFD & COMBUSTION ENGINEER / PhD

« CFD studies for the development of new-generation aircraft propulsion systems »

For over 20 years, GDTech has been supporting major aerospace and energy related firms and helping ambitious projects come true, especially for combustion related applications. GDTech is a certified supplier for the entire Safran group and a leading supplier regarding high-fidelity simulations. We are also involved in R&T projects, either as a leader, partner or subcontractor, and work in close relation with several combustion focused national laboratories.
Following its development in the aeronautics sector, GDTech France is hiring an engineer or PhD specialized in fluid dynamics and combustion to carry out LES (Large Eddy Simulation) and RANS activities on applications related to new-generation aircraft engines

In this context, you will work as an engineer within the Engineering and Numerical Simulation department, reporting directly to the head of the combustion group at GDTech France. In this role, you will be required to:
• Carry out RANS & LES numerical simulation studies applied to combustion, two-phase flow aerodynamics, thermals, on various topics (injector design, pollutant prediction, engine performance, staged combustion, etc.)
• Analyzing CFD computations results, and comparing them to experimental data
• Implementing new LES numerical methods and frameworks to meet new industrial needs (alternative fuels, hydrogen, etc.)
• Occasionally, take part to the development of Python specialized inhouse codes
• Participate in GDTech or customer R&T projects
• Work in collaboration with other GDTech technical experts
• Support the customer in its product development process, and attend technical meetings.

This position is located in Seine-et-Marne (77), where you will be in direct contact with one of our customers, an aircraft engine manufacturer

• You hold an engineering degree or equivalent (Master’s degree) in fluid dynamics (combustion, aerothermal), ideally supplemented by a PhD with a specialization in combustion. You have a good knowledge of reacting flows, thermodynamics, and experience in turbulent combustion using RANS software (FLUENT, OpenFoam, StarCCM+, etc.) or, ideally, LES (AVBP, Yales2, CONVERGE).
• Professional experience in a similar role in an industrial environment (aeronautics, defense and space, industrial burners) or in a research laboratory would be appreciated
• Knowledge of the ANSYS suite (SpaceClaim, Fluent Meshing, Fluent), ANSA and CATIA V5 tools would be a plus. Programming skills, particularly in Python, would also be useful.
• You have a particular interest in airplanes, helicopters or aeronautics in general.
• Other useful skills for this position include : good adaptability, strong interpersonal skills, a genuine team spirit and collaborative attitude, a sense of confidentiality, priorities and responsibilities.
• You are rigorous, motivated, and committed to participating in the development of an SME in a spirit of collective growth, promoting GDTech’s image of expertise and relevance to our customers.
• Candidates must be eligible to access regulated technologies (EU) to comply with export controls regulations and the handling of sensitive data.
• Language skills:
  • French fluency is essential
  • English fluency
