Job description

In an always more competitive environment, engine performances, and so the low pressure compressor, need to be improved continuously.

This induces first a desire of efficiency improve, of course ; but this efficiency cannot go on without keeping high operability and stability on its components, in a tight development schedule.

It is then mandatory to find the right balance between physically accurate numerical model, and CPU cost of the computations.

You should apply for this internship if :

  • you're looking to increase your knowledge both in the field of internal aerodynamics as well as advanced CFD,
  • you want to work in within a challenging environment with strong interactions between various expertises
  • you want to develop yourself in a young and dynamic team of skilled engineers
  • Job requirements

    Good knowledge of aerodynamics or fluid mechanics. Basic knowledge in turbomachinery,internal aerodynamics and computational fluid dynamic is a plus.

    Good physical sense and capability to work within a team are mandatory skills. The day-to day language is French, but a good knowledge of English is required.

    Internship objectives :

    1.To implement in the standard studies a wall model in order to decrease the mesh size and thus the CPU cost

    2.To define the adequate mesh strategy to use with wall models in order to maintain the accuracy level of the computation

    3.To test the wall modelling on various industrial case to determine the interest of the methodology

    4.As an potential extension, study the available modified wall models to cope with surface roughness effect and apply it to a compressor case

    Specificity of the job

    Tools to be used (if necessary) :

    AutoGrid from Numeca for meshing, elsA from ONERA for CFD computations, Safran group internal computation chain, Ensight and in-

    house codes for post-treatment.
