I – NEW POSITIONS FOR PHDs AND POSTDOCs AT HZDR

———————————————–
(from Sven Eckert, Germany)

  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

II – LECTURER/SENIOR LECTURER IN FLUID MECHANICS

———————————————–
(from Alban Potherat, UK)

LECTURER/SENIOR LECTURER IN FLUID MECHANICS

Salary per annum : £29,344-£37,346 (L)/£35,247-£50,187(SL)

The Fluid Dynamics Group within the Applied Mathematics Research Centre at Coventry University is seeking to appoint a Lecturer/Senior lecturer in fluid mechanics to support its growing activities in the fields of geophysical fluid dynamics and turbulence.

The Group currently comprises 7 Staff and PhD students and runs projects combining theory, numerical simulations and experiments, supported by a number of grants from research funding bodies and international partnerships. It has priority access to extensive on-site high performance computing provisions and runs two major experimental facilities: a magnetohydrodynamics lab, which includes a large bore, purpose-built 8T superconducting magnet, as well as a modular experimental platform for the study of turbulence in liquid metals, in collaboration with the French CNRS in Grenoble.

The successful candidate will be expected to primarily focus on research, and will benefit from a reduced teaching load for this purpose. He/she will help to develop existing themes in geophysical fluid dynamics and turbulence, and to extend the group’s existing long-term international collaborations (with the CNRS amongst others). At the same time, the appointee will be encouraged to start new directions of research, within the wide remit of fundamental and applied Fluid Dynamics.

Research activity will involve leading and co-leading projects both theoretical/numerical and experimental in nature, supervising PhD students and post doctoral researchers, and actively seeking funding, from national and international funding agencies, or from private funders.

The smaller teaching role will involve helping to develop and teach courses at Master level in Applied Mathematics/Physics, as well as some undergraduate teaching.
Candidates should hold a PhD or equivalent in any area of fluid mechanics/physics and have an established track record of publishing their work in the best international journals in the discipline. Evidence of previous commitment to attract research funding from major agencies or private funders will be an advantage.
The post will be for an initial period of four year and will be made permanent on satisfactory performance.<

Informal inquiries are encouraged, please contact Professor Alban Potherat (alban.potherat(at)coventry.ac.uk, +44(0)2477 65 88 65 (email only from April)),

Application deadline 19/04/2013

Application must be made online at
