Our society is transitioning to a low-carbon renewable energy system where solar and wind energy are becoming increasingly important. Because of the inherent intermittent nature of solar and wind energy and the difficulties to store vast amounts of electrical energy over a long time, suitable energy carriers are indispensable. An important energy storage solution is to convert electrical power from renewable resources into hydrogen through water electrolysis. To make this green hydrogen economically competitive, the water electrolysis process should move towards higher current densities without increasing the cost of the materials used. For this purpose, more fundamental knowledge of flow and transport phenomena near electrode surfaces is needed. The research programme “bubble dynamics in electrolysis” aims at unravelling the different phenomena and to give specific direction to enable a step change rather than small evolutionary improvements.
The programme is divided into four interlinked sub-projects of which one project is advertised here. Experimental and numerical tools will be developed to study the key transport phenomena at different length scales, i.e. those of bubble nucleation, Marangoni flow phenomena between a hydrogen bubble and an electrode, and the interaction between multiple bubbles and its effect on the mass transfer.
In the current project we will focus on the direct numerical simulation of mass transfer, Marangoni flow phenomena and electric potential in the electrolyte flow surrounding bubbles growing at an electrode. It is our plan to develop a finite difference solver based on curvilinear grids, possibly overset on a Cartesian background grid.
We are looking for an experienced candidate with a background in mechanical or chemical engineering or physics or applied mathematics. The candidate is preferred to have knowledge of fluid mechanics combined with strong programming and mathematical skills and a good physical intuition. The ideal candidate has excellent scientific skills as well as excellent soft skills related to verbal and written communication.
We offer a challenging job for four years in a highly motivated team at a dynamic and ambitious University. You will be part of a highly profiled multidisciplinary collaboration where expertise of a variety of disciplines comes together. The TU/e is located in one of the smartest regions of the world en part of the European technology hotspot ‘Brainport Eindhoven’; well-known because of many high-tech industries and start-ups. A place to be for talented scientists!
The gross monthly salary in accordance with the Collective Labor Agreement of the Dutch Universities (CAO NU), starts with € 2.325,- in the first year to € 2.972,- in the fourth year. Besides this the TU/e has holiday- and end-of the year allowances, an excellent package of attractive benefits for employees and a modern sports complex. Assistance for finding accommodation can be given. Especially for PhD students the TU/e also offers opportunities for personal development. We do this by offering every PhD student a series of courses that are part of the Proof program as an excellent addition to your scientific education.
