Research assistant in Computational Fluid Dynamics (m/f/d)

within the research project “Particle-resolving simulations of Cohesive Sediment Dynamics (PRO-MUD)” at the TU Braunschweig funded by the Emmy-Noether Programme of the German Research Foundation (DFG).
We invite applications for a TV-L 13 position, 100% for 3 years with a possible extension of a fourth year, starting March 1st 2020.

Cohesive sediments such as clays and silt are ubiquitous in aquatic environments. Understanding, predicting and controlling the transport of this fine-grained sediment in open waters has therefore been of vital interest. Unlike its cohesionless counterpart, e.g. sand, cohesive sediments interact by attrac-tive forces that give rise to flocculation. These flocs can grow in size much bigger than the individual grain size of primary particles, which changes the hydrodynamic behavior of the sediment. The posi-tion will deal with the software development and enhancement of a computational code for the simula-tion of cohesive sediment dynamics towards the capabilities of handling cohesive particle-particle interactions. This includes the application of this newly developed code on massively parallelized su-percomputers and the analysis of simulation data by means of self-developed postprocessing rou-tines.

The PhD candidate will be responsible for the maintenance and the enhancement of an in-house C-based computational code for the simulation of multiphase flows. The enhancements of the code will require an in-depth understanding of fluid mechanics, multiphase flows, and the development of nu-merical algorithms with programming languages for massively parallelized applications (C or Fortran and Message Passing Interface). Automatic methods to analyze large amounts of data will be devel-oped and applied (Matlab, Python, or similar as well as Tecplot, Paraview or similar). A detailed com-parison to experimental benchmark data will be conducted to validate the newly developed code.
All applicants should have an MSc degree in civil engineering, mechanical engineering, computer sci-ence or a closely related field. We encourage applications from dedicated with strong quantitative skills as well as good writing skills in English (German is an asset), who enjoy working in the multi-disciplinary team of the PRO-MUD project. Strong experience in computational fluid dynamics and programming are essential, as well as the willingness to visit collaborating research groups within and outside of Germany.
We offer an interdisciplinary, international work environment with the opportunity to pursue a doctoral degree. An extensive exchange of the research assistant with the collaborating research teams at the University of California Santa Barbara (USA), the University of Aberdeen and the University of Stuttgart (Germany) is foreseen.

TU Braunschweig is an equal opportunity employer and is committed to increasing the proportion of women scientists. Consequently, we actively encourage applications from qualified women. We also welcome applications from candidates with severe disabilities who will be given preferential considera-tion in case of equal qualification. During the application process, personal data will be stored elec-tronically. Applications from international scientists are welcome.
Please send your application including a cover letter, CV, an example of your own scientific writing, a statement of research interests, certificate & transcript of your highest degree earned and the names and contact details of at least two potential references in one pdf-file to Bernhard Vowinckel (b.vowinckel@tu-braunschweig.de).

Application deadline is December 20th 2019.

Application costs can not be reimbursed.
