Job title:
Postdoc Interaction of Hydraulic Polymetallic-Nodule Collectors with the Seabed Sediment

Job description
Offer DescriptionAiming for a carbon-free future, societies steadily move toward electric transport and machinery utilizing renewable energy. Consequently, there is an increased demand for critical materials such as copper and cobalt to realize such energy sources. Since the terrestrial mineral deposits are depleting, the deep-sea floor has recently been receiving great attention from industrialists and scientists. Immense amounts of strategic metals and rare-earth elements are embedded into the ocean floor, particularly in potato-sized concretions termed polymetallic nodules. These nodules are rich in crucial metals such as cobalt, copper, manganese, and nickel, and companies are keen to get their hands on these nodules.Hydraulic Coandă-effect-based collectors are most widely considered, because of their indirect contact with the seabed. However, such collectors disturb the seabed; sediment is inevitably picked up and collected together with the nodules during the mining process. The collected sediment is discarded at the rear of the collector. Consequently, a sediment plume is formed, which could travel long distances away from mining sites, disrupting aquatic ecosystems in their track.The current understanding of the interaction between Coandă-effect-based collectors and the seabed sediment remains scant. The available approach to predict seabed disturbance is through empirical relations. The aim of this postdoctoral position is to improve these relations leading to a more unified physical understanding of the interaction between the collector and seabed sediment. To this end, computational fluid dynamics (CFD) simulations will be run and validated with recently-acquired experimental data. Following that, data-driven and sparse identification techniques will be applied to discover the underlying physics.RequirementsSpecific Requirements
- PhD degree in Dredging Engineering, Civil Engineering, Hydraulic Engineering, Ocean Engineering or a related field of study.
- Proven affinity with sediment erosion/transport.
- Experience in CFD modelling.
- Background in machine learning is highly desired.
- Excellent communication skills and ability to work independently as well as in a team.
- Excellent command of English, written and spoken.
