Mechanical Design Engineer

CFD Engineer

About the Role
As a CFD Engineer focusing on turbochargers, you will support the aerodynamic and thermo-fluid development of compressor and turbine components—from early concept to series release. You will build robust, automated simulation workflows, correlate results with hot-gas-stand tests, and collaborate closely with platform, validation and application engineering to deliver best-in-class turbocharger performance and durability.

Key Responsibilities

·        Plan, execute and document CFD studies for turbocharger components (compressor wheel, turbine wheel, volutes, VTG, bearing housing flow) including compressible, transient, and conjugate heat transfer cases.

·        Select appropriate physical models (RANS/URANS/SBES/LES, turbulence, sliding mesh/mixing plane) and verify grid/time-step independence with sound y+ management and GCI methodology.

·        Set up automated pre/solve/post pipelines (Python/bash), parameter sweeps and design-of-experiments; maintain version-controlled templates and reports.

·        Correlate simulation results to hot-gas-stand measurements; drive root-cause analyses and propose design countermeasures.

·        Perform optimization against efficiency, pressure ratio, surge margin and NVH constraints across multiple operating points.

·        Support forced response analysis / structural risk assessment through CFD→FEA coupling in collaboration with structural analysis.

·        Collaborate cross-functionally with platform owners, validation and application teams; contribute to internal best-practice guides and knowledge bases.

·        Communicate results clearly to technical and non-technical audiences, including gate reviews and customer meetings as required.

Required Qualifications

·        Master’s degree (or higher) in Mechanical/Aerospace Engineering or similar, with focus on turbomachinery/fluids.

·        3+ years of hands-on CFD experience for rotating machinery with compressible aerodynamics (shock/expansion, tip leakage, stall/choke).

·        Proficiency with Ansys CFX/Fluent and/or STAR-CCM+ and/or OpenFoam; strong meshing skills, CAD interfaces (Creo/NX/CATIA).

·        Scripting/automation in Python; batch/scheduler usage; Git-based version control.

·        Demonstrated test correlation experience (hot-gas-stand/compressor & turbine map), uncertainty analysis, and robust reporting.

·        Professional English communication skills (written and verbal).

Preferred Qualifications

·        Experience with wheel and volute optimization

·        Background in turbo integration, thermal management and materials

·        Acoustics (broadband/tonal) and 1D–3D co-simulation for pulsating turbine inflow.

·        Exposure to forced response workflows (CFD→FEA) and durability risk screening.

·        Data-driven methods/ML surrogates for rapid map prediction and design space exploration.
