A Snapshot of Your Day

You will be part of the Fluid Dynamic Lab team as Master Student. We are offering a position that will experimentally investigate the effect of additively manufactured (AM) induced roughness on the local heat transfer. The experimental method has been developed and verified and is called the Surface Roughness Heat Transfer method (SRHT).

The SRHT method examines local heat transfer on upscaled AM surfaces and with that, the opportunity to study the effects of different surface parameters related to AM roughness. At the beginning of the test, the test coupons are at a known uniform temperature and are subjected to a sudden step change in flow temperature. The time-resolved surface temperature will be measured using an IR camera. By assuming local constant values of the heat transfer coefficient over time, the heat equation will be solved using an in-house conjugate FEM solver. This rig is involved in several research collaborations with universities.

The project is performed at our lab facilities for the duration of 7 months with start in October 2026.

How You’ll Make an Impact

The master thesis project is well structured, and you will have an experienced supervisor. The project plan usually follows the points below:

• 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. The goal of each of our Diploma Thesis’ is to create a work result that it might be worth publication and some examples of previous student projects from the lab can be found in the Journal of Turbomachinery, ASME Turbo Expo and International Journal of Heat and Mass Transfer (TURBO-14-1171, GT2014-25619, GT2015-42475, GT2017-64143, GT2018-75019, DOI:10.1016/j.ijheatmasstransfer.2024.125532).

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.
