Functieomschrijving

Versatile alternative energy solutions are of paramount importance to counteract climate change in the benefit of future generations. Solar and wind energy play an important role in this goal, but their availability is intermittent. To mitigate this, electrical energy can be suitably converted and stored in energy carriers such as hydrogen. However, the efficiency of current electrolytic hydrogen production processes is hampered by the presence of bubbles blocking the electrode surface and lowering interfacial mass and heat transfer. In this project, we aim to better understand the nucleation, growth and detachment of gas bubbles in the pores and at the surface of porous electrodes.

To address this problem, we will develop a Lattice Boltzmann code to simulate multiphase flow (gas-liquid-solid), with reactive surfaces (modelling adsorption, reaction, desorption phenomena), multi-component diffusion (e.g. Maxwell-Stefan like) and including the effects of electric fields and charges. The simulation results will aid in the development of a predictive model for bubble nucleation rates at electrode surfaces. This model and the simulation results will support experiments and macroscopic simulations performed by our partners at TU Eindhoven and University of Twente. As such, this project will involve close interaction within a team of researchers.

Functie-eisen

We are looking for an excellent PhD candidate with a strong background in (applied) physics, chemical Engineering, or a related discipline. Ideally, you are familiar with electrochemical and transport phenomena and the statistical mechanics of charged particles (e.g. Poisson-Boltzmann), and proficient with coding in advanced languages like C++. Prior experience with Lattice Boltzmann simulations will be considered a great advantage. Good verbal and written communication skills are essential.

Conditions

TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers childcare and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. 

As a PhD candidate you will be enrolled in the TU Delft Graduate School. TU Delft Graduate School provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and a Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills.
