PhD: Boundary-Layer Transition Over Periodic Roughness

ONERA; France; On-site; EUR 34,000 - 38,000; Full time

Job summary

ONERA in Meudon, France, invites applications for a PhD position in fluid mechanics focusing on boundary-layer transition induced by surface roughness, under the FairCFD network. The project combines Bloch theory and homogenization to develop efficient methods for predicting perturbation amplification in periodic roughness.

The candidate will work within the Departement of Aerodynamics, Aeroelasticity and Acoustic and contribute to a Marie Skłodowska-Curie Actions Network.

Qualifications

• PhD applicant in fluid mechanics or related field.
• Experience with boundary-layer theory and stability analysis is advantageous.
• Strong programming and high-performance computing skills.

Responsibilities

• Develop analytical and reduced-order models for boundary-layer transition over rough surfaces.
• Implement Bloch theory and homogenization approaches for periodic roughness.
• Track resolvent modes and compare with high-fidelity simulations.
