We have an opening for a PhD student researcher to join a cutting-edge research project conducted within an European consortium of research and industrial institutions about carbon caputure using fluidised bed technology.
The project focuses on the numerical modelling of the hydrodynamics of fluidized beds including heat and mass transfer. However, common CFD-models require sufficiently fine numerical grids to resolve all relevant heterogeneous structures such as bubbles which requires excessive computational resources to research industrial scale processes. To overcome these severe limitations, we have recently proposed a novel numerical method following single phase turbulence theory. Similar to single phase turbulence models it allows much coarser gird resolutions resulting in speed-ups of two orders of magnitude and more.
The focus of this position is to further develop this theory for reactive gas-particle flows, which is essential for the carbon capture process. The selected PhD student will work as part of a multidisciplinary team of experienced researchers, closely collaborating with a PostDoc focus on the collective motion of particulate flows.
PhD researcher position in the field of modelling of gas particle flows for a full-time, three-year-position at the Department of Particulate Flow Modelling for the projects "FlexCSAR" within the framework of the European CEPT partnership.
