The Institute of Fluid Dynamics invites applications as
PhD Student (m/f)
The position will be available from 1 January 2018. The employment contract is limited to three years. The regular weekly working time will be 29.25 hours. The salary is based on the collective agreement TVöD-Bund. The place of work is Dresden.
Metal recovery from slags uses the top submerged lance technology (www.outotec.com) in which gas is injected into a slag melt via a submerged lance from above. ln order to improve the energy and resource efficiency of the process, the announced position shall perform experimental modelling of this process. Extensive experiences exist at HZDR on the handling of the room-temperature model melt GalnSn. The work in frame of this position is a joint project of the Institute of Fluid Dynamics at HZDR with the Helmholtz Institute Freiberg for Resource Technolgy which also belongs to HZDR. The general goal is to bring together basic fluiddynamic methods with practically relevant resource technologies, and to transfer the results to industrial partners.
- high grades in master´s degree in Mechanical Engineering, Process Engineering or Physics
- knowledge of fluid mechanics or measurement of flows
- knowledge of metallurgical processes are advantageous
- experimental modelling of the two-phase flow gas-slag using the room-temperature liquid metaI GalnSn
- measurement of the gas bubbles and the flow in the melt using available ultrasonic and X-ray measurement techniques
- extension of the model experiments to include chemical reactions of the gas phase (oxygen added) with the metaI melt and investigation of the mass transport of the resulting oxides. Alternatively injection of solid particles and measurement of their transport.
