Master Thesis: CFD Modelling of Flow Around a Turbine Blade Tip

A Snapshot of Your Day

In this master thesis, you will investigate the complex flow around a turbine blade tip using computational fluid dynamics (CFD). The aim is to establish a robust modelling approach that can reliably capture the relevant blade-tip flow phenomena and support future engineering assessments. You will work in close collaboration with specialists in turbine heat transfer, fluid dynamics, and numerical simulation. The assignment combines method development, CFD analysis, validation, and engineering interpretation in an industrial gas-turbine environment.

How You’ll Make An Impact

• Review relevant blade-tip flow physics, modelling approaches, and available reference material.
• Define an appropriate CFD model for the flow around the blade tip and through the tip-clearance region.
• Assess how modelling choices and numerical settings influence the predicted flow field and key engineering quantities.
• Compare simulation results with available reference data to evaluate and validate the methodology.
• Document the recommended modelling approach, its limitations, and the conditions under which it can be applied.
• Present the results and provide recommendations for continued development and future use.

What You Bring

• You are studying for a master’s degree in Mechanical Engineering, Aerospace Engineering, Energy Engineering, Engineering Physics, or a related field.
• You have a solid foundation in fluid mechanics and an interest in turbomachinery, aerodynamics, heat transfer, or numerical simulation.
• You have experience with CFD, or a strong motivation to develop your CFD skills during the thesis.
• You approach technical problems analytically and work in a structured and systematic way.
• You can communicate technical results clearly in written and spoken English.
• The thesis may be carried out by one student or jointly by two students.

Expected outcome

The thesis is expected to deliver a documented and validated CFD methodology for modelling the flow around the blade tip. The work should clarify the sensitivity of the results to important modelling choices and provide practical guidance for future blade‑tip analyses.

About The Team

You will join a collaborative team of engineers and specialists working with gas‑turbine heat transfer, fluid dynamics, and CFD. You will receive technical guidance throughout the thesis while contributing to a relevant industrial challenge linked to turbine performance, durability, and efficiency.
