RWTH Aachen - Applied Geophysics and Geothermal Energy & AICES
The institute for Applied Geophysics and Geothermal Energy performs application-oriented research in the fields of geothermal energy, numerical simulations of flow and transport processes, petrophysics and seismic imaging. The institute hosts an international and interdisciplinary team of PhD students and postdocs and operates a well-equipped petrophysics laboratory.
The Junior Research Group Geofluiddynamics at the Aachen Institute for Advanced Study in Computational Engineering Science (AICES) has expertise in developing mathematical and computational models for complex phase-change processes. Furthermore, the group is actively engaged in various glacial exploration initiatives.
Jülich Supercomputing Centre operates supercomputers of the highest performance class in Europe and provides computer capacity for scientists at the Research Centre Jülich (FZJ), at universities and research laboratories in Germany and in Europe - as well as for industrial partners.
The Jülich Aachen Research Alliance Centre for Simulation and Data Sciences (JARA-CSD), combines several former initiatives (AICES, JARA-HPC, CompSE etc.), aiming to foster interdisciplinary education and research between RWTH Aachen University and FZ Jülich.
Geothermally induced melting of large ice sheets from below is a key factor for glacial dynamics and sub-glacial landscape evolution, yet not well understood until now. Investigating the interplay between geothermal heat transfer, deep-to-shallow, saline groundwater circulation and melting at the base of an ice sheet requires the capability to simulate phase-change processes coupled to naturally convecting, complex geometry porous media flow. This PhD project is centered around the development of a melting and freezing module for the hydrothermal in-house code SHEMAT-Suite, and its application to study the genesis mechanisms of subglacial meltwater channels during the last ice-age.
The PhD research consists of
Model development: The system’s physical regimes, its corresponding model formulation and alternative options for the numerical discretization will be studied.
HPC code implementation: A performant scheme will be developed that complies with the framework of SHEMAT-Suite and exploits the HPC infrastructure at FZ Jülich.
Data integration and ensemble set-up: Subsurface data from repositories as well as seismic profiles from the North German Basin shall be integrated into a geological model. An ensemble will be set up to account for data uncertainty.
Model-based hypothesis testing: Finally, the complete workflow shall be utilized to investigate various alternative genesis scenarios for subglacial tunnel valleys.
The PhD project will be located at the School for Simulation and Data Sciences (SSD), the successor of the Aachen Institute for Advanced Study in Computational Engineering Science (AICES), and at the Institute for Applied Geophysics and Geothermal Energy. The candidate is jointly supervised by Dr. Sönke Reiche (Applied Geophysics and Geothermal Energy) and Priv.-Doz. Dr. Julia Kowalski (Geofluiddynamics), both of whom head junior research groups at AICES. The project furthermore benefits from a strong collaboration with Prof. Stefan Kollet at FZ Jülich.
We are looking for a candidate with a strong interest in geoscientific research and a university degree (master or comparable) in geophysics / physics / applied mathematics or in a related discipline. Experience in coding and with large scientific software is a definite plus.
What we offer:
The position is until 30.09.2021 / 3 years and is to be filled by October 1, 2018. The standard weekly hours will be 25,88 hours. 65%
The successful candidate has the opportunity to pursue a doctoral degree.
The salary corresponds to level EG 13 TV-L.
