Job summary

The Centre for Industrial Mechanics at SDU in Sønderborg invites applications for a 2-year postdoctoral position focusing on Multiphysics Modelling of Bubble Transport and Electrochemical Processes in Alkaline Electrolysers. Starting Oct 1, 2026, or as soon as possible, with start date agreed.

You will develop simulation tools for multiphase CFD and current distribution, validate with experiments, and collaborate with SDU, DTU, and Stiesdal Hydrogen to reduce CAPEX and advance cassette design.

Qualifications

PhD in engineering, computational science, physics or related discipline.
Background in computational fluid dynamics (CFD).
Experience in multiphase flow and/or electrochemical transport modelling.
Experience with numerical simulation software such as ANSYS, COMSOL, or OpenFOAM.
Programming skills in Python, C++, or equivalent languages.
Strong teamwork, communication, and independent research skills.
Proficient in English (spoken and written).

Responsibilities

Develop and apply simulation methods for multiphase transport and current distribution in electrolyzers.
Investigate bubble-buoyancy-driven internal electrolyte circulation.
Quantify transport processes affecting mass transfer and electrochemical performance.
Integrate computational and experimental results to advance mechanistic understanding and predictive modelling.
Collaborate with academic and industrial partners.
Mentor and supervise students (PhD, MSc, BSc) on related research questions.
Publish research results in peer-reviewed journals and present at international conferences.
Contribute to research funding applications and assist with teaching activities as relevant.
