Test Engineer - Master Thesis Student · Siemens Energy

Seven months embedded at Siemens Energy Finspang in the Fluid Dynamic Lab. Conducted numerical investigation of steady-state thermo-fluid performance of a reducer geometry for a high-temperature dynamic pressure sensor calibration rig (Pulsatorn). Built compressible CFD and conjugate heat transfer models in ANSYS Fluent (k-omega SST), conducted three-level mesh independence study, and applied Biot number analysis to decompose thermal performance. Identified flow-regime asymmetry between geometry variants (Ma 0.990 near-choked vs Ma 1.006 supersonic vena contracta). Also commissioned NI-DAQ measurement chains, modified LabVIEW VIs, ran independent test campaigns at up to 700 C, and conducted a formal root cause analysis of a heater failure resulting in an approved project scope revision. Used Siemens NX and Teamcenter PLM2020 throughout. Supervisor: Prof. Jens Fridh, KTH. Thesis: TRITA-ITM-EX 2026:14.

Scope & limitations

The Siemens thesis is a numerical investigation with measurement-chain commissioning. Heater failure limited sustained high-temperature comparison; the work does not establish full experimental validation. Independent thermal models retain their own verification limits.

This dossier groups related public records. It does not imply equal depth across every tool or independent validation of every result. Source case studies remain authoritative; restricted inputs and private documents are not included.
