Siemens Energy

The proposed master thesis aims to address how to improve the accuracy of CFD prediction using a minimum number of cells. The methodology will be applied to the cooling of the SGT-800 combustor liners and the combustor heat shield, utilizing both convective cooling enhanced with rib turbulators and impingement cooling. In short, we are interested in finding a methodology to obtain thermal boundary conditions that result in metal temperatures in a more cost-efficient manner, which will be compared to measurement data recorded on a test for an instrumented prototype engine. This project offers an exciting opportunity to learn about gas turbine engines and contributes to the advancement of combustion research and the development of more efficient and environmentally friendly combustion systems.

This project is well-suited for two candidates, with each individual focusing on one of the respective methods.

How You’ll Make an Impact

• Evaluate test cases of rib cooling compared to correlations from the open literature.
• Investigate what mesh strategy that obtains best accuracy using minimal number of cells using both RANS and LES simulations.
• Apply the selected methodology to a part of the SGT-800 combustor.
• Evaluate the improved methodology compared to Siemens Energy standard approach, i.e. accuracy versus number of cells.

What You Bring

• Currently enrolled in a master's program in mechanical engineering, aerospace engineering, or a related field.
• Strong background in heat transfer, FEM and/or CFD analysis.
• Background in programming.
• Proficiency in numerical modelling and simulation software.
• Good problem-solving, analytical, and communication skills.
