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.
Job Responsibility:
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
Requirements:
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
