*Job description*
Water electrolysis using green electricity 
for production of green hydrogen will be 
important in the transition towards a 
renewable energy future. Hydrogen bubbles 
help drive the flow of electrolyte, 
required for cooling. Because they are 
insulating, they also hinder the transport 
of ions and increase the resistance. To 
minimise energy losses and maximise 
natural convection, you will make, 
validate, improve, and use a comprehensive 
computational multiphase flow model 
including heat and mass transport.

As part of a consortium of Dutch 
universities and companies HyPro, 
(https://groenvermogennl.org/project/hypro
-onderzoek-naar-technische-risicos-en-
kostenverlaging-van-groene-waterstof/) you 
will look at flow phenomena in good 
contact with researchers from the 
companies AVOXT and NEWES. These companies 
develop membraneless and high-pressure 
tubular natural-convection driven 
electrolysers, respectively. Due to their 
innovative nature, there are still several 
open questions that modelling can help 
answer.

A turbulent Euler-Euler two-fluid model or 
mixture model is envisioned, coupled to 
transport of current, heat and dissolved 
gas. The model will be implemented in 
commercial software like COMSOL, Ansys 
Fluent, or an open-source code like 
OpenFoam. Working models for various 
aspects of electrolyser modelling are 
already used in our groups and may be 
expanded upon.

You will be part of the lively research 
groups of Willem Haverkort 
(http://jwhaverkort.weblog.tudelft.nl), 
including a mix of experimental and 
computational students, PhDs, and other 
researchers. Occasional work visits or 
consortium meetings to the collaborative 
partners are foreseen. Various 
experimental projects are running in 
parallel, and you are encouraged to 
regularly leave your computer, go into the 
lab and directly compare your results to 
experiments. Within Delft there is a 
flourishing community of researchers 
working on various types and aspects of 
electrolysis (https://www.tudelft.nl/e-
refinery).

We can use your enthusiasm for CFD to help 
the energy transition and look forward to 
meeting you and work on this challenging 
topic together!


*Job requirements*
As our new colleague you:

Hold a PhD degree in an engineering or 
scientific discipline.
Have a proven track record in 
computational modelling and fluid 
mechanics.
Are a highly motivated and self-driven 
researcher, capable of working both 
independently and as part of a team.
Have an excellent command of written and 
spoken English.
 
Experience with Ansys Fluent, OpenFoam, or 
COMSOL or multiphase flow modelling is a 
big plus.
