(from Gunter Gerbeth, Dresden, Germany)

29 PhD and 11 Scientist positions offered in frame of the German Helmholtz Alliance LIMTECH

The German Helmholtz Association established a so-called Helmholtz-Alliance in the field of “Liquid Metal Technologies” (LIMTECH), starting on Oct. 1, 2012 for the period of 5 years. Mainly based on the Helmholtz Centres in Dresden-Rossendorf (HZDR) and Karlsruhe (KIT) and in very close cooperation with Universities (Dresden, Freiberg, Ilmenau, Hannover, Potsdam, Goettingen, Aachen, Coventry, Riga) and further Helmholtz partners (Juelich, DLR) the Helmholtz Alliance shall intensify the research in this field. The alliance is coordinated by Dr. Gunter Gerbeth (g.gerbeth(at)hzdr.de). LIMTECH consists of 14 projects and a Young Investigator Group. The experimental and theoretical-numerical research works range from basic studies on turbulence, magnetically induced instabilities and dynamos, to measurement techniques for liquid metal flows, the use of liquid metals in future solar power stations or liquid metal batteries, up to applied investigations for the improvement of metal casting or crystal growth technologies. LIMTECH involves 29 PhD and 11 scientist positions. Details about LIMTECH, the various projects and the corresponding position offers please find at

Workshop “Tangled Magnetic Fields in Astro- and Plasma Physics”

Posted by on 13 July 2012 Comments Off on Workshop “Tangled Magnetic Fields in Astro- and Plasma Physics”

The above meeting will be held in autumn in the International Centre for Mathematical Sciences (ICMS) in Scotland as a satellite workshop of a six-month program on

TOPOLOGICAL DYNAMICS IN THE PHYSICAL AND BIOLOGICAL SCIENCES

16 July – 21 December 2012

Isaac Newton Institute for Mathematical Sciences, Cambridge, UK

WWW.NEWTON.AC.UK/PROGRAMMES/TOD

The Workshop in Edinburgh will focus on the research exploiting topological and geometrical concepts in the study of morphology and evolution of magnetic fields in astrophysics and plasma physics. The topics will include:

  • Dynamo action associated with chiral turbulence, in planetary and solar contexts;
  • Eruption of solar/stellar fields through chromospheres and coronae;
  • Braiding of the coronal field due to footpoint motion;
  • Spontaneous field discontinuities (current sheets) and coronal heating;
  • Magneto-rotational instability (MRI) in accretion discs, and associated transport of angular momentum;
  • Magnetostatic equilibria in toroidal fusion plasmas; their stability and containment characteristics.

For more information, including the list of invited lectures, please visit www.icms.org.uk

If you would like to participate and be considered for a contributed talk or poster, please complete the  on-line application form.  The  deadline for applications is

31 August 2012

We encourage early applications. Registration may have to be closed before the deadline as the number of Participants is limited by the size of the lecture hall.

PHD ON MAGNETOHYDRODYNAMIC TURBULENCE AT LNCMI-GRENOBLE/COVENTRY UNIVERSITY (UK)

Posted by on 1 June 2012 Comments Off on PHD ON MAGNETOHYDRODYNAMIC TURBULENCE AT LNCMI-GRENOBLE/COVENTRY UNIVERSITY (UK)

(from Alban Potherat, Coventry, UK)

Applications are invited for a PhD position in experimental fluid mechanics at The Grenoble High Magnetic Field Laboratory (GHMFL, Grenoble, France), under a co-tutelle agreement with Coventry University (UK). The subject is the experimental investigation of turbulence in liquid metals under the influence of very high magnetic fields. Turbulence is one of the major remaining challenge from classical physics. This work will target the mechanisms of the transition between the two and three-dimensional states of turbulence. This hot question of fundamental fluid mechanics has direct implications for several modern problems such as the optimisation of heat extraction in future nuclear fusion reactors, or the challenge posed by the dynamo effect that is responsible for the existence and the dynamics of the magnetic field of the Earth, but also on the dynamics of oceans and atmospheres.

The PhD student will take part in an experimental project headed by A. Potherat, where liquid metal turbulence is generated in a closed vessel placed within a large magnet hosted at the GHMFL, in Grenoble, who delivers some of the highest magnetic fields in the world. Since magnetic fields mainly push the flow towards two-dimensional states, they provide a convenient way to control the 2D-3D transition, so as to analyse its mechanisms in detail. The flow is diagnosed using advanced metrology techniques such as Ultrasound velocimetry and electric potential velocimetry. The student will be in charge of running the next phase of this experiment and analysing the results.

Successful applicants should hold a Master or Engineering degree with a solid background in fluid mechanics, and be highly motivated by the conduct of highly technical projects. The PhD student will be attached to CoventryUniversity’s Post-GraduateSchool but based in Grenoble (France) with a few trips to the UK every year. The PhD student will receive a grant of approximately 17k Euros per annum, entirely free of tax or any other deductions.

A good command or either French or English is an essential requirement. Applicants should address their CV, a recent set of marks/rankings and the name of at least one referee to Dr. Alban Potherat, CoventryUniversity (alban.potherat(at)coventry.ac.uk). Please note that only EU citizens are eligible.

Informal inquiries are welcome, please contact Alban Potherat (+44(0)2476 88 88 65), or Francois Debray, LNCMI francois.debray(at)lncmi.cnrs.fr +33(0)476 88 12 44

PostDoc Position at University of Leeds, UK

Posted by on 3 May 2012 Comments Off on PostDoc Position at University of Leeds, UK

University of Leeds, Department of Applied Mathematics. 3 year NERC-funded postdoc position.

Applications are invited for a research fellowship funded by the Natural Environment Research Council (NERC). The project will investigate the convectively driven dynamics of the Earth’s fluid outer core and, in particular, the nature of the reversals of the Earth’s magnetic field. The aim will be to determine the various forms of dynamo action that are possible and to locate the parameter regimes in which reversals may occur, thus improving our understanding of the reversal mechanism. The post will involve the modification and running of existing convective dynamo codes in Cartesian and spherical shell geometries. You will work in close contact with the principal investigator (PI) Professor David Hughes as well as with Professor Chris Jones in the Department of Applied Mathematics. A PhD (or PhD submitted) in the relevant discipline, e.g. Computational Fluid Dynamics or Earth Sciences with computational experience or Astrophysical Fluid Dynamics is essential. Interpretation of the results in terms of geomagnetic data will be performed with the investigators and with Professor Cathy Constable of the University of California, San Diego.

University Grade 6 (£24,520 – £29,249 p.a.) or University Grade 7 (£30,122 – £35,938 p.a.) It is likely that an appointment will not be made above £31,948 p.a. due to funding limitations.

Informal enquiries may be made to Professor David Hughes, tel +44 (0)113 343 5105 email d.w.hughes(at)leeds.ac.uk

Closing Date: 11 June 2012

Interviews are expected to be held 9 July 2012
