Master Thesis: 3D CFD Modeling of Thermosiphon Heatsinks

Bygg, teknik och hantverk · Bygg- och industriteknik · Maskinteknik

I korthet

Master Thesis project focused on 3D CFD modeling of thermosiphon heatsinks, a passive cooling solution for high-power electronics, using the Volume of Fluid (VOF) method. The role involves analyzing performance, evaluating design parameters, and potentially comparing simplified models, based at Ericsson AB in Kista, Stockholm, starting January 2027.

Ansvarsområden

Review thermosiphons, two-phase cooling, and relevant CFD modeling approaches.
Develop and run 3D VOF simulations of thermosiphon heatsinks.
Analyze evaporation, condensation, liquid return, vapor transport, and overall flow behavior.
Study the effects of operating conditions, geometry, and filling ratio on thermal performance.
Evaluate thermal resistance, temperature distribution, and key flow characteristics.
Document modeling challenges and best practices, and provide recommendations for future thermosiphon design.
Optionally compare simplified segment-based models with detailed VOF simulations.

Krav

Pursuing a Master’s degree in Mechanical Engineering, Engineering Physics, Energy Technology, Applied Physics, or a related field.
Previous experience with Computational Fluid Dynamics (CFD) is required.
Good understanding of fluid mechanics, thermodynamics, and heat transfer.
Strong analytical and systematic problem-solving skills.
Ability to work independently and communicate technical findings clearly.

Önskade kvalifikationer

Experience with multiphase flow, phase-change phenomena, programming, or numerical methods is an advantage.

Förmåner

Outstanding opportunity to use skills and imagination to push the boundaries of what's possible.
Be challenged in a team of diverse innovators.
Work on solutions for some of the world's toughest problems.
