With renewable electricity from wind and solar becoming cheaper and higher in demand, storage of electrical energy is become more important. One of the cheapest yet highly energy efficient ways to store electricity on a large scale is with redox flow batteries. In a particularly promising type, hydrogen and bromine are created from water and hydrogen bromide during charging, and converted back during discharge. To improve performance, durability, and cost effectiveness, membrane-less designs have been proposed and successfully tested. Separation of reaction products can be effected by ensuring thin laminar boundary layers, see for example Braff et al., Nature Comm., 4, 2346 (2013) and Suss et al. RSC Adv., 6 (2016).

In this PhD project a comprehensive computational model will be developed to test and optimize several designs and innovations. The focus will be on the physics and understanding, rather than on programming or numerical mathematics. Therefore, use will be made of readily available solvers like COMSOL Multiphysics or, if needed, OpenFOAM. An important goal is to formulate guidelines for design, preferably in the form of mathematical formulas or engineering correlations.

The PhD position will be part of a larger European effort to improve and scale this technology up. Therefore, the insights gained from modelling will be immediately put to use in designing prototypes, and experimental data that can be used for validation and calibration will become available during the course of the project. In case a candidate is exceptionally motivated and successful, a combination with experimental research can be discussed. The ideal starting data will be somewhere early 2020.


We are looking for a highly self-motivated, independent, and assertive candidate (f/m) with a sharp mind for critical and creative thinking as well as good communication skills in English.  

An MSc in an applied science or an engineering discipline like applied physics or mathematics, mechanical-, aerospace-, or chemical engineering or equivalent is required as well as a proven affinity with and skill for mathematical and computational modelling.
