Siemens Energy

A Snapshot of Your Day

To meet the required lifetime of components in the turbine hot gas path, different cooling techniques must be used to decrease their metal temperature. Internal cooling channels running through blades and vanes are equipped with additional cooling features that work by increasing both the turbulence and the heat transfer area locally. To create an optimal cooling design, the local heat transfer coefficient (hereby noted as HTC), temperature and pressure distributions must be predicted correctly.

As a master thesis student, you will join the Fluid Dynamics Lab team to experimentally investigate the thermal performance of matrix cooling technology.

The Matrix Cooling Rig is designed to evaluate the heat transfer and pressure loss characteristics of different geometric configurations. This will help determine their relative significance and advance the current state of the art in this field.

By combining spatially-resolved surface temperature measurements using Thermo Liquid Crystals (TLCs) with simultaneous measurements of temperature, pressure, and mass flow within the test object, you will be able to evaluate dimensionless pressure loss and the Nusselt number as functions of the Reynolds number. An in-house conjugate FEM solver will be used to solve the relevant conservation equations.

The project will be conducted in our laboratories over a period of 20 weeks or seven months depending students availability, starting in the time period January - March. This timeframe will allow you to implement improvements in test methods and collect results for validation.

How You’ll Make an Impact

The master thesis project is well structured, and you will have a experienced and competent supervisor. The project plan usually follows the path where you will be responsible for:

• Literature review
• Test rig preparation for testing
• Perform testing
• Analysis of test results
• Apply changes on the test rig, test procedure or analysis to improve the results
• Final report/presentation writing

During the thesis you will acquire improved skills in dimensional analysis, data acquisition, heat transfer calculation and mass flow/pressure/temperature measurements. Basic knowledge in additive manufacturing will be obtained. An assigned experienced supervisor will support you during the whole period.

What You Bring

Your profile should show:

• Courses on:
• gas fluid dynamics
• heat transfer
• dimensional similarity
• numerical methods
• Knowledge in Matlab/Python.
• Fluency in English language are required both in speech and writing.
• It is appreciated if you have had laboratory testing experience

About the Team

The Measurement and Component Testing team is composed of highly experienced and knowledgeable test technology engineers and measurement technology engineers. We are around 20 team members, and we have four labs where we perform prototype design validation. We are part of the R&D department at Siemens Energy AB in Finspång and therefore our test measurements and methods are always evolving to meet new design validation demands and new technology developments. We are responsible for validation of both full engine prototypes as component prototyping.

Our Gas Services division offers Low-emission power generation through service and decarbonization. Zero or low emission power generation and all gas turbines under one roof, steam turbines and generators. Decarbonization opportunities through service offerings, modernization, and digitalization of the fleet.
