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 research 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. These will be communicated in several publications in international peer-reviewed journals.

The 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.

The research will be performed under the supervision of and in collaboration with Willem Haverkort, at the process & energy department, liaising with the melody project partners, and embedded in the Delft e-refinery community.

We are looking for a self-motivated, independent, and assertive candidate (f/m) that can think creatively and critically and has good communication skills in English. 

A PhD 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. Preferably the candidate has previously performed research into computational modelling involving transport and fluid flow and, ideally, electrochemical reactions. 

Fixed-term contract: 2+ years.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities (salary indication € 3.491 - € 4.402 per month). The TU Delft offers a customisable compensation package, a discount on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged.

For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation. An International Children's Centre offers childcare and there is an international primary school.

This postdoc position has a fixed-term contract of between 2 and 2,5 years, depending on previous experience.
