The Johannes Kepler University Linz (JKU Linz) and the Technische Universität Wien (TU Vienna) are joining forces to establish a Doctoral College for Computational Sustainability, combining the strengths and competences of complementary disciplines at both universities, and aiming to create and approve transdisciplinary knowledge in key research areas of computational sustainability. The aspirational vision of the Doctoral College is a world in which computational sciences significantly contribute, support, drive and foster global, regional and national efforts towards sustainable development.
For this joint Doctoral College, we invite applications from outstanding candidates eager to contribute to cutting-edge research in computational sustainability.
The successful candidate will pursue a dissertation project with working title
Sustainable Water Recovery via Advanced Flotation and Computational Modelling,
see a summary of the planned project https://www.jku.at/institut-fuer-verfahrenstechnik/forschung/forschungsprojekte/computational-sustainability/
The dissertation project will be co-supervised by Univ.-Prof. Dr.-Ing. Mark W. Hlawitschka (JKU Linz), and Univ.Prof. Dr.-Ing. Alfredo Soldati (TU Wien).
The Institute of Chemical Process Engineering (Verfahrenstechnik) of the Johannes Kepler University Linz is equipped with laboratory and technicum space to design processes from laboratory scale towards pilot plant scale. In recent years, a test stand for nozzles to generate the finely dispersed bubbles was established. A pilot plant facility for the investigation of flotation was jointly build up with the Institute of Measurement Technology was established.
At the Institute of Fluid Dynamics and Heat Transfer, TU Vienna, strong expertise on computational simulations in turbulence is available. Both have access to the austrian scientific cluster (https://asc.ac.at/home/). JKU Linz will provide office and laboratory space, analytical instrumentation, and in-house software tools for CFD and image analysis. TU Vienna will contribute access to the turbulence tank and developed simulation codes. Cross-institutional scientific support will be continuously provided.
