*Research Associate/Postdoc (m/f/d)*
A member of the Helmholtz Association of German Research Centers, the
HZDR employs about 1,200 people. The Center's focus is on
interdisciplinary research in the areas energy, health and matter.
The Institute of Fluid Dynamics is conducting basic and applied research
in the fields of thermo-fluid dynamics and magnetohydrodynamics in order
to improve the sustainability, the energy efficiency and the safety of
industrial processes.
As part of the Institute, the Department of Magnetohydrodynamics,
invites applications as Research Associate/Postdoc (m/f/d).
The position will be available from 1st January 2020. The employment
contract is limited to three years.
Tasks:
The appearance of thermal superstructures in turbulent convection within
very low Prandtl number fluids will be investigated experimentally in a
large aspect ratio domain. The experiments will be conducted using the
liquid metal Gallium-Indium-Tin (GaInSn) that has a Prandtl number of
𝑃𝑟 ≈ 0.03. Combined temperature and velocity measurements will provide
detailed information about turbulent, convective superstructures and
their dynamics. A novel Ultrasound-Doppler-Array technique will be used
to measure for the first time two dimensional velocity vector fields of
the superstructures in a turbulent liquid metal convection.
The project includes the following tasks:
* preparation and operation of a Rayleigh-Bénard convection cell for
liquid metal
* measurements of global transport laws for heat and momentum
* simultaneous measurements of flow velocity using ultrasound Doppler
velocimetry and temperature distribution using thermocouples
* investigation of the three-dimensional flow structure and dynamics
of turbulent superstructures
* comparison of the results to direct numerical simulations (carried
out by project partners)
Requirements:
* completed doctorate in physics, mechanical engineering or comparable
qualification
* a strong technical and physical understanding is mandatory
* background knowledge on thermal convection would be advantageous
We offer:
* high scientific professional networking as well as scientific excellence
* internationality and diversity
* interesting and diverse tasks, flexible working hours, salary based
on the collective agreement TVöD-Bund
* equality of opportunity and family-friendly structures, corporate
health management
* attractive work and research terms in a highly motivated team
Kindly submit your completed application (including cover letter, CV,
diplomas/transcripts, etc.) only via our Online-application-system.
