PhD Studentship: Computational Modelling of Hydrodynamical Scour
University of Exeter, UK
Deadline: Friday, November 06, 2015

This PhD studentship is part of a larger EPSRC-funded project assessing the risks to masonry bridges from flooding. Failure of bridges, which are vital links in the national transport network, can lead to loss of life and significant damage, have severe knock-on effects on local and national economies, and hamper post-flood rescue and recovery efforts. The project will use a combination of experimental investigations and numerical modelling to characterize the hydrodynamic effects of debris blockage, which is one of the major causes of bridge failure during floods, and implement findings within guidance for practitioners.

You will lead the work-package on numerical modelling within the project. You will be responsible for creating the CFD models required to simulate flow under masonry bridges and around bridge piers with floating debris blockage, particularly investigating the hydrodynamic effects of scour and pressure forces on bridges. You will develop novel approaches to modelling scour using advanced techniques such as dynamic meshing and modern turbulence models and LES, and compare results with in-house experimental data to validate the results. You will be part of a multidisciplinary research team that is composed of leading researchers from Exeter, Heriot-Watt and Belgrade, and will be assisted by an industry-led steering committee including consultants, asset owners and stakeholder groups involved in bridge management in the UK.

Applicant criteria: applicants should have or expect to achieve at least a 2:1 Honours degree, or equivalent, in Mechanical or Civil Engineering, Physics or Mathematics. Applicants will need a good understanding of fluid dynamics and mathematical modelling; experience of Computational Fluid Dynamics (CFD) and the OpenFOAM code would be beneficial; understanding of bridge scour or sediment transport techniques would also be beneficial.

Contact for informal enquiries: Professor Gavin Tabor (email; g.r.tabor@ex.ac.uk). To apply please fill out the web form at http://www.exeter.ac.uk/studying/funding/award/?id=1815

PostDoc Position: Whole Engine Body Force Modeling
ISAE-SUPAERO / DAEP, France
Deadline: Thursday, December 31, 2015

Engine modeling is usually achieved through thermodynamic 1D modeling. This approach is limited for innovative engine architecture assessment or when distorsion effects have to be accounted for. Full CFD modeling remains too expensive for routine design use. In this context, representing turbomachinery rows by source term, the Body Force Modeling (BFM) approach, is an effective alternative.

The goal of the post-doc is to apply the BFM approach to achieve CFD simulation of the complete flow path of a turbofan engine. The test case is a high-bypass ratio geared turbofan, for which experimental data and CFD results are available for validation. The target is to develop and apply the methodology to the windmilling (engine out) regime of the turbofan. The main challenges are: 1/ treating the windmilling regime with BFM; 2/ develop BFM models for turbines; 3/ integrate several BFM models in full engine calculations and 4/ account for combustion in the calculation with source terms.

The successful candidate is expected to have: - A PhD in computational fluid dynamics. - Good knowledge of turbomachines and propulsion systems. - Good knowledge of CFD. Experience with a general 3D CFD code. - Basic programming knowledge (post-processnig with Python will be developped). - Team working capability, initiative and problem solving skills.

The position is for 2 years (with a 1 year additional renewable period). Salary: to be discussed, but standard for a postdoc in France. Starting date: as early as possible

Flow Interaction at Storm Surge Barriers with Hydroturbines
Delft University of Technology, Netherlands
Deadline: 15-11-2015

Job description
Recently, the implementation of hydroturbines in storm surge barriers has been recognised as a viable option for sustainable energy production. Initiatives in this direction are presently ongoing (Brouwersdam and Eastern Scheldt barrier, the Netherlands). The hydroturbines affect the flow through and around the barrier, and the tidal exchange in the delta. Knowledge on this matter is needed to gain optimum performance of the turbines and to warrant structural integrity of the barrier, while respecting the morphological and ecological values of the delta. The situation is characterised by the widely different spatial scales that are involved, varying from a few metres at the barrier to several kilometres within the delta. The simultaneous representation of these flows in computational models, needed for engineering studies, is therefore difficult. To understand the interaction between the small- and larger-scale water motion, laboratory experiments are foreseen, supplemented with field measurements obtained during a pilot study at the Eastern Scheldt barrier. Applying new computational techniques, the local flow at the barrier will be embedded in numerical models covering the regional water system. The project is funded through a NWO grant.


Requirements
We are looking for a PhD candidate with an MSc degree in a relevant discipline such as hydraulic engineering or (geophysical) fluid mechanics. Candidates holding a degree in related disciplines such as applied mathematics or experimental/numerical fluid mechanics and with a strong interest in the envisaged applications are also eligible. A strong interest in quantitative (data) analysis and numerical modelling, and experience with scientific research (e.g. publications, projects) are an advantage. You should have a strong motivation for science and engineering (driven by curiosity), and have an open mind. Critical (self-)reflection and the ability to work independently are mandatory. We expect you to contribute to general tasks in the section such as teaching. Proficiency in the English language (spoken and written) is a requirement


Information and application
For further information, you can contact Dr. R.J. Labeur, Assistant Professor, r.j.labeur@tudelft.nl, or Prof. W. S. J. Uijttewaal, Professor of Experimental Hydraulics, w.s.j.uijttewaal@tudelft.nl.

Numerical modelling of flocculating sediment transport
Katholieke Universiteit Leuven, Belgium
Deadline: Sun, 31 Jan 2016

Project
The BRAIN.be project INID67 (2015-2018), funded by the Belgian Science Policy Office (BELSPO) is a collaboration between Royal Belgian Institute for Natural Sciences (RBINS) - OD Nature, KU Leuven and IFREMER (France), coordinated by Michael Fettweis (RBINS). It focusses on the EU Marine Strategy Framework Directive (MSFD) indicators 6 'Sea-floor integrity' and 7 'Hydrographical conditions'.
One of the key research topics is the incorporation of flocculation into the SPM modelling of fine-grained cohesive sediment transport, in order to improve the prediction of the formation and resuspension of fluid layers as found near the Belgian coast. The major aim of this task is the implementation of a multi-class population balance flocculation model, as proposed by Lee et al. (2011), into the 3D TELEMAC (v7) software and application of the model to the Belgian coast. The flocculation model should be adapted to work with three (instead of two) floc classes (micro-flocs, macro-flocs and mega-flocs, formed seasonally during algae bloom periods). The task requires making changes into to the source code, testing the code, calibration and validation of the model.
The candidate will be working in a multi-disciplinary team-working environment, collaborating with other researchers in our research group who use the TELEMAC suite in various other projects. In particular, an adapted version of the flocculation model will need to be developed to be used in the application of microplastics transport in the Baltic Sea in the framework of the JPI Oceans project WEATHER-MIC.

Profile
Candidates should hold a degree of master (MSc) in engineering (or equivalent), with specialization in Hydraulic, Environmental, Oceanographic, Civil or Mechanical engineering, with experience in computational fluid dynamics (CFD) and willing to study and modify the model source code (FORTRAN programming). Experience in population balance modelling is an asset. The candidate shall be able to carry out research investigation independently, and willing to work in a multidisciplinary team. He/she should be proficient in English, have excellent scientific writing, planning and communication skills, and be an enthusiastic team player.
Students from non-EER countries should count on requiring to follow a predoctoral program of 6-12 months, before being allowed to the (4 years) PhD program. The duration and content of this predoctoral year depends on proven research experience and international publications.

Applications, including a motivation letter, CV, diploma transcript(s) and names and contact details of (at least) three reference persons, should be sent to
