Postdoc CFD Water Electrolysis

Join our effort to improve innovative alkaline water electrolyser designs through computational modelling!

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, 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, 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.

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.

TU Delft (Delft University of Technology)

We believe this makes our work more innovative, the TU Delft community more vibrant and the world more just. Together, we imagine, invent and create solutions using technology to have a positive impact on a global scale. That is why we invite you to apply. Your application will receive fair consideration.

Faculty Mechanical Engineering

From chip to ship. From machine to human being. From idea to solution. Driven by a deep-rooted desire to understand our environment and discover its underlying mechanisms, research and education at the ME faculty focusses on fundamental understanding, design, production including application and product improvement, materials, processes and (mechanical) systems.

ME is a dynamic and innovative faculty with high-tech lab facilities and international reach. It’s a large faculty but also versatile, so we can often make unique connections by combining different disciplines. This is reflected in ME’s outstanding, state-of-the-art education, which trains students to become responsible and socially engaged engineers and scientists. We translate our knowledge and insights into solutions to societal issues, contributing to a sustainable society and to the development of prosperity and well-being. That is what unites us in pioneering research, inspiring education and (inter)national cooperation.

Conditions of employment

• Duration of contract is 2 years.
• A job of 32-40 hours per week.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. The TU Delft offers a customisable compensation package, discounts on health insurance, and a monthly work costs contribution. Flexible work schedules can be arranged.
