About The PhD project
The increase in heat transfer rate in various applications and devices calls for new ways of efficient device cooling to increase their reliability and efficiency. Suspensions of dispersed nanoparticles in common fluids and refrigerants, so-called ‘nanofluids’, offer a high potential for controlling the heat transfer and increasing heat exchange efficiency. In particular, nanofluids are suited for small-volume cooling devices based on microfluidic chips as well as porous materials. However, the stability of nanofluids is still a limiting factor which decreases their efficiency in engineering applications. Accumulation at the walls and agglomeration among particles are common issues caused by interactive forces, which effect the dispersion, rheology, and overall performance of those suspensions. Hence, knowledge about the interaction of nanomaterials with the liquid is of fundamental importance.
The PhD position is centered around studying experimentally fundamental processes of nanofluid multi-phase flow in model microfluidic systems. Nanofluid fabrication, high-resolution Helium ion microscopy, dynamic light-scattering particle characterization and other microscopy techniques will be used for that at NanoSYD in Sønderborg. In addition, it is intended to implement time-resolved neutron imaging at the European Spallation Source (ESS), located in Lund/Sweden. Neutron imaging is an ideal tool for visualizing nanofluid multi-phase flow, particularly to investigate the boiling mechanism in terms of bubble dynamics because of the high interaction cross-section of neutrons with liquids. Experimental work is to be combined with numerical modelling of fluid dynamics.
About SDU NanoSYD
We focus our research on improving the performance of device incl. their reliability and stability, as well as on up-scaling, and bridge the academic field to industrial development. Here, devices from organic molecules and polymers include solar cells, transistors, diodes, and sensors.
Thin films are grown from organic and inorganic compounds. Organic molecules self-assemble into nanoscopic aggregates with special optical features. We investigate their properties by diffraction techniques, scanning probe microscopies such as scanning electron and scanning ion microscopies, and coherent as well as incoherent optical techniques. Furthermore, we focus on basic and applied research in nanophotonics and nanoplasmonics, which are interdisciplinary research areas concerned with the generation and manipulation of electromagnetic excitations at the sub-wavelength scale.
The PhD fellow will work in a trans-disciplinary team dedicated to micro- and nanoscience. We offer an international and stimulating environment with state-of-the-art infrastructure and equipment for conducting research of high quality.
The successful candidates will be affiliated with the nanoscience centre NanoSYD at the Mads Clausen Institute, University of Southern Denmark which is located at the Faculty of Engineering on the international campus in Sønderborg, Denmark.
The project is related to research activities at the recently established Centres for Industrial Electronics and Industrial Mechanics and will involve close cooperation with the vibrant industrial environment in the cross-border region Denmark-Germany.
The work is funded by SOLID, a Danish national lighthouse cluster in the field of hard materials. At the cluster, cutting-edge research in 3D imaging, image analysis and modelling is performed, with the intention to include future neutron imaging at the European Spallation Source in Lund/Sweden.
Applicants are required to have a master’s degree (equivalent to a Danish master’s degree) at the time of enrollment and employment.
Employment of a PhD fellow can only happen after the Head of the PhD School has approved the candidate for admission to the PhD school. Employment and enrollment will cease without further notice at the end of the period.
A PhD fellow is not allowed to have any kind of sideline employment, while enrolled as PhD fellow at the faculty.
Employment is governed by the Protocol on PhD Research Fellows signed by the Danish Ministry of Finance and the Danish Confederation of Professional Associations. Please check links for more information on salary and taxation.
The successful candidate will be enrolled at SDU in accordance with Faculty regulations and the Danish Ministerial Order on the PhD Programme at the Universities (PhD order), read more here.
