POSTDOC POSITION AT TU ILMENAU

Posted by on 9 January 2014 Comments Off on POSTDOC POSITION AT TU ILMENAU

———————————————–
(from Christian Karcher, Ilmenau, Germany)

The Research Training Group (RTG) on Lorentz Force Velocimetry and Lorentz Force Eddy Current Testing at Ilmenau University of Technology offers

1 full-time postdoctoral position
in theoretical and computational magnetohydrodynamics.

The RTG is sponsored by the Deutsche Forschungsgemeinschaft DFG. Final funding approval for this position is expected 08 May 2014. The position is thus available as of 01 June 2014. The position lasts two years. Extension up to a total of 4½ years is possible. The position is paid according to TVL E14 scale (approx. 45.000 – 55.000 EUR per year before tax). It is strictly dedicated to promote and qualify women in science.

The measurement of flow velocities in hot and aggressive liquids like metal melts and molten glass is a grand challenge in industrial fluid mechanics. A physically closely related challenge is the detection of deeply lying flaws and inhomogeneities in electrically conducting solid materials. Since 2004, scientists at Ilmenau University of Technology have been developing two novel technologies termed Lorentz force velocimetry and Lorentz force eddy current testing to meet these challenges. Both technologies are based on measuring the Lorentz forces that are induced by the interaction of electrically conducting moving substances and magnetic fields.

Within the RTG, the basic physics of these technologies shall be explored by performing high-precision model experiments, high-resolution numerical simulations, and intense analytical modeling. The RTG provides a creative and inspiring environment, excellent laboratory facilities, state-of-the-art scientific computing facilities, and the possibility of collaborating with industry and with foreign institutions. Further details can be found at www.tu-ilmenau.de/lorentz-force.

Successful candidates for the position should have

• an excellent doctoral degree, preferably in engineering, physics, or applied mathematics,
• an excellent knowledge of the English language,
• a high motivation for interdisciplinary work in an international scientific team,
• a strong background in modeling of multi-physics problems.

Experience in theoretical and computational magnetohydrodynamics is desirable but not required.

Handicapped applicants with identical qualification will be considered with priority. Special services are available concerning social matters.

Applicants should e-mail the complete set of documents (see www.tu-ilmenau.de/lorentz-force) in PDF format as soon as possible but not later than 30 April 2014 to lorentz-force(at)tu-ilmenau.de.

Preliminary information is given by the RTG Head, Professor Jörg Schumacher and the RTG Scientific Coordinator, Dr. Christian Karcher, who can be contacted electronically under joerg.schumacher(at)tu-ilmenau.de and christian.karcher(at)tu-ilmenau.de, respectively.

Successful candidates are expected to have experience/background in the area of experimental fluid dynamics/heat & mass transfer. Experience in experimental studies of liquid metals (PbLi, InGaSn, NaK, Hg), especially in the presence of a strong magnetic field, and working knowledge of liquid-metal flow diagnostics, such as ultrasound velocimetry and potential probes, is desirable. Considerations will be given to both recent university graduates (Ph.D. is required) and senior scientists with a multi-year experience in the field.

The position is available starting from September 01, 2013. Applications or questions about the position should be sent to Sergey Smolentsev (sergey(at)fusion.ucla.edu) and copy to Mohamed Abdou (abdou(at)fusion.ucla.edu).

New Positions for PhDs and PostDocs at HZDR

Posted by on 15 April 2013 Comments Off on New Positions for PhDs and PostDocs at HZDR
  1. The Helmholtz Centre Dresden-Rossendorf (HZDR) invites for applications concerning a PhD position within a project devoted to the further development of the Contactless Inductive Flow Tomography (CIFT) for flow measurements in electrically conducting flows. The availability of appropriate measurement techniques is a necessity for any experimental work on liquid metal technologies. Exposing the flow of liquid metals like steel or silicon to an externally applied magnetic field, electrical currents are induced which give rise to a perturbation of the applied field. This flow induced field perturbation, which is detectable outside the fluid volume, contains information about the flow structure and can be exploited to reconstruct the velocity field. Previous tests at laboratory scale revealed a great potential of the CIFT method for the online monitoring of flow structures in real industrial processes.Applicants must have a master degree in physics, electrical engineering or fluid engineering.
  2. The Helmholtz Centre Dresden-Rossendorf (HZDR) invites for applications concerning a PhD position within a project devoted to experimental investigations with respect to the behaviour of gas bubbles and bubble swarms in liquid metal flows. Many technical applications in power engineering, metallurgy and casting rely on liquid metal two-phase flows. In metallurgy, gas injection is routinely applied at various stages to promote chemical reactions and to stir the melt for reducing temperature and/or concentration gradients together with promoting an effective removal of impurities. On the other hand, gas entrainment into liquid metal coolants is an essential safety issue in the design of liquid metal cooled fast reactors. Visualizations of liquid metal two-phase flows can be obtained by means of X-ray radioscopy. The formation, the coalescence and breakup of gas bubbles will be observed in low melting point alloys. The method delivers data about the size, the velocity and the trajectory of the bubbles. This information will be used by another partners in the project to develop advanced models of bubble coalescence and breakup for liquid metals.Applicants must have a master degree in physics, electrical engineering or fluid engineering.
  3. The Helmholtz Centre Dresden-Rossendorf (HZDR) invites for applications concerning a postdoc position within a project devoted to the development of casting technologies ODS steels. Oxide dispersion strengthening (ODS) of high-Cr steels is a promising way to get materials for high-temperature applications. The mechanical and corrosive properties are significantly improved compared to present-day steels. However, it is difficult to disperse ceramic particles uniformly in liquid metals because of their poor wettability and their large surface-to-volume ratio, which easily induces agglomeration and clustering. In case of nano-dispersed aluminum alloys the homogeneous distribution of nano-particles has been obtained by ultrasonic vibration of the melt. This project focuses on the problem whether alternating electromagnetic forces can be designed in such a way that an intense vibration of the melt can be achieved, similar to the case of ultrasonic vibration. The possibility of creating electromagnetically induced pressure waves in a metal melt shall be investigated.Applicants must have a PhD in physics or engineering with a strong background in material science, fluid mechanics or magnetohydrodynamics.All position are available from June 1, 2013 until May 31, 2016. A prolongation until October 2017 is conceivable.

Applications should be sent to Sven Eckert (s.eckert(at)hzdr.de) or Gunter Gerbeth (g.gerbeth(at)hzdr.de) before May 31st.

Many thanks and best regards
Sven
