Siemens Energy

As part of the compressor aerodynamics group, you’ll dive into the challenges of maintaining high performance in axial compressors operating under real-world conditions. Over time, blade surfaces degrade due to erosion from particles, fouling from contaminants, and increased surface roughness from wear and corrosion. These effects can significantly reduce compressor efficiency and reliability.

In this master’s thesis, you will investigate how these degradation mechanisms impact aerodynamic performance. Using CFD simulations and literature data, you will quantify performance losses, identify critical blade regions, and explore mitigation strategies. The goal is to develop a robust simulation framework that can predict performance decay regarding aerodynamic and support future design improvements.

How You’ll Make an Impact

• Conduct a comprehensive literature review on erosion, fouling, and surface roughness effects in axial compressors.

• Develop CFD models to simulate blade degradation scenarios using commercial tools such as ANSYS CFX or Trace.

• Perform parametric studies to assess the sensitivity of compressor performance to varying degrees of surface degradation.

• Validate simulation results against published experimental or numerical data.

• Identify critical regions on compressor blades most susceptible to performance decay.

• Propose design or operational strategies to mitigate degradation effects.

• Normalize results to ensure confidentiality while maintaining technical integrity.

What You Bring

• M.Sc. student in aerospace engineering, mechanical engineering, engineering physics, or similar.

• Experience with CFD tools (e.g., CFX, STAR-CCM+, TRACE).

• Programming skills in Python and/or MATLAB.

• Ability to work independently and proactively seek solutions.

• Structured and clear communicator.

• Interest in turbomachinery and aerodynamic performance
