Postdoc in the Field of Reactive Transport Phenomena

Forschungszentrum Jülich - FZJ - Helmholtz Association

Jülich, Germany

Work group:

IEK-6 Nukleare Entsorgung und Reaktorsicherheit

Area of research:

Scientific / postdoctoral posts

Job description:

Your Job:

The long-term evolution of chemical conditions in a geological repository cannot be fully assessed by respective laboratory experiments alone, but can be addressed by combination to state of the art simulations of the flow regimes in fractured or porous media coupled to the relevant geochemical processes, a research field of increasing importance with respect to the safety of nuclear waste disposal. In this context we apply innovative experimental and computational approaches to analyse and interpret complex coupled thermal-hydraulical-mechanical-chemical (THMC) processes relevant to radionuclide release and transport in the near- and far-field of geological repositories for radioactive wastes. The work to be performed includes

Investigation of the hydrodynamics of porous and fractured rocks using μCT and/or datasets from other imaging techniques Derivation of constitutive equations for the description of coupled processes and implementation in existing and newly developed reactive transport codes Reactive transport modeling in porous media, focusing on precipitation/dissolution and sorption at the continuum and pore scale Verification and validation of simulation approaches Publication of results in peer-reviewed journals

Your Profile:

Graduate of a university with excellent academic degree and subsequent doctorate in Applied or Computational Mathematics, alternatively in Physics, Chemistry, or Earth/Environmental Sciences Substantial knowledge of flow and transport processes in porous media Substantial experience in computational fluid dynamics Substantial experience in scientific programming languages such as C, C++, Python or Fortran Ability to work in high performance computing environment is desirable Computer vision and experience in image processing and visualization is desirable Ability to work in a multidisciplinary team Excellent English communication and writing skills

Our Offer:

International, interdisciplinary working environment on an attractive research campus, ideally situated between the cities of Cologne, Düsseldorf, and Aachen Attractive work and research terms as well as interesting and diverse tasks in a highly motivated Team High scientific professional networking as well as scientific excellence Internationality and diversity A comprehensive further training programme Flexible working hours and various opportunities to reconcile work and family life Limited until 30.06.2021 with possible longer-term prospects Full-time position with the option of slightly reduced working hours Salary and social benefits in conformity with the provisions of the Collective Agreement for the Civil Service (TVöD)

Forschungszentrum Jülich aims to employ more women in this area and therefore particularly welcomes applications from women.We also welcome applications from disabled persons.
