PhD Position Multiscale Modelling of Sorption-Enhanced CO2 Hydrogenation Reactors

Faculty/Department: Faculty of Mechanical Engineering

Hours per week: 36–40

FTE: 0.9–1.0

Job description

The research programme CO2URAGE, funded by the Dutch funding organisation NWO in the framework of the Perspectief Programme, targets the conversion of intermittent electricity to platform chemicals and fuels making use of dynamically operated processes. This is a promising route to alleviate net congestion and make more effective and economic use of renewable electricity without an unnecessary discarding of generated power. This four year’s PhD position is aimed at developing multiphase models to predict the dynamics and performance of sorption-enhanced CO2 hydrogenation reactors. An important feature is that the reactor should be heated electrically and should be scalable.

The PhD student will develop three-dimensional models to predict the hydrodynamics and heat/mass transfer in a complete reactor containing millions to billions of particles with basic wall heating. The precise type of reactor will be chosen in collabaration with other partners within this project. In case a (moving of fixed) bed is chosen, a coarse-grained CFD-DEM model or an Eulerian model will be developed, possibly making use of correlations from particle-resolved simulations. In case a fluidized bed is chosen, a traditional Eulerian Two-Fluid model (TFM) will be compared with a novel Lagrangian Continuous Particle Model (CPM). Initially, engineering correlations will be employed to describe the internal heat and mass transfer within the particles. Later, more accurate single-particle model results will be incorporated. The most suitable model will be expanded to investigate the efficiency of other electricity-based heating solutions such as microwave heating or electro-acoustic heating.

At TU Delft, the modelling work will be accompanied by another PhD student and postdoc who will carry out experimental work, which will allow for validation of the models. You will collaborate with experts from TU Delft, TNO and several large and SME companies involved in the programme.

Job requirements

• An MSc degree in Mechanical engineering, Chemical engineering, Applied physics, or related field is required.
• Knowledge and proven experience with reactor modeling and multiphase CFD simulations.
• A critical and inquisitive attitude with regard to obtained results is expected, which translates into formulating new research questions.
• Ability to function both in a team and independently.
• Good communication skills. Fluent in English, both spoken and written. Willing to learn the Dutch language.
