Postdoc in Experimental Studies of Turbulence – Volumetric Particle Tracking Velocimetry – DTU Construct

Company:

Danmarks Tekniske Universitet

Job description

Job Description:DTU Construct is offering a postdoc position in Particle Tracking Velocimetry measurements and analysis of small (dissipation rate) and large (global) scale turbulence. The position is offered at the DTU Turbulence Research Laboratory and PDJF Turbulence Centre of Excellence.Within the scope of the project, you will conduct groundbreaking experimental work using PTV measurements of canonic turbulent flows, in particular on the turbulent round jet. The measurements are centered around studying both the global flow behavior and the small-scale structure (detailed studies of the dissipation rate and its transport properties). The measurements will be carried out in two separate experiments. You will also support analysis of the measurement data in novel ways to test the validity of the existing theories of turbulence and attempt to synthesize new theory based on the empirical result. You will be part of a research group that works on different aspects of turbulence, including theory, simulations and experimental work.Responsibilities and qualifications
The position is focused on acquisition and analysis of PTV measurements, for which you will be responsible. The position includes updating and completing the experimental setups, where necessary, to be able to successfully carry out the measurements. You will be working in close collaboration with our instrumentation group and our optics specialist, who will assist in these tasks. Furthermore, the Department has a workshop that can help with constructing parts when needed. You is also expected to work in close collaboration with other Postdocs and members in the group, with a common focus on analysis and obtaining novel results and insights that will be used to increase our understanding of the actual physics of turbulence.Also, you will be co-responsible for setting up new and maintaining collaborations with leading groups in different fields.You may also be given the possibility to develop leadership skills and experience in co-advising PhD- and MSc-students.You are expected to be a team player, while also being able to work independently and take ownership of, and responsibility for, the project, to be able to carry out the tasks.Candidates should have a PhD degree in experimental fluid mechanics and (highly preferably) a solid background in Particle Tracking Velocimetry. You should also have a solid understanding of fluid mechanics to be able to interpret, understand and analyze the measurements.You should have:

• A solid experimental fluids background, preferably including extensive experience with Volumetric Particle Tracking Velocimetry measurements
• Experience and a general sense of laboratory work and the different challenges that may arise (electrical, mechanical, theoretical, optical etc.)
• An understanding of optics related to PTV measurement and preferably beyond
• Sufficient knowledge of signal processing and data interpretation, to be able to recognize limitations in the measurements
• A theoretical background on turbulent jet (and other thin shear) flows in particular, as well as on turbulence in general is highly beneficial
• Experience and proficiency with big data handling, parallel processing, GPUs (e.g. CODA) and analysis of extensive datasets is advantageous
• Experience with DaVis software and methods such as Shake the Box and VIC# and data assimilation methods is advantageous

You should also enjoy teaching and supervision of project students on various levels. Flexibility and self-motivation are the desired skills at DTU. In addition, we expect you to be interested in collaboration and to take personal responsibility for the assigned tasks.

• You are motivated by both individual and team accomplishments
• You are focused on the process as well as the outcome
• You strive to develop talent amongst others
