DTU Compute’s Sections for Mathematics, would like to invite applications for a 3-year PhD position starting September 1, 2017. The project is financed by the Danish Council for Independent Research.

Our department DTU Compute is an internationally unique academic environment spanning the science disciplines mathematics, statistics and computer science. At the same time we are an engineering department covering informatics and communication technologies (ICT) in their broadest sense. Finally, we play a major role in addressing the societal challenges of the digital society where ICT is a part of every industry, service, and human endeavour.

DTU Compute strives to achieve research excellence in its basic science disciplines, to achieve technological leadership in research and innovation, and to address societal challenges in collaboration with partners at DTU and other academic institutions, nationally and internationally, and, equally important, with industry and organizations. We communicate and collaborate with leading centres and strategic partners in order to increase participation in major consortia.   

DTU Compute plays a central role in education at all levels of the engineering programmes at DTU - both in terms of our scientific disciplines and our didactic innovation. 

Project Description
When a fluid flows around a bluff body, a remarkable organization of the motion may occur. In the wake, rotating structures known as vortices appear and follow the flow downstream in a regular pattern. If the bluff body oscillates, the pattern may be very complex, and is known as an exotic wake. The purpose of the project is to enhance our understanding of the structures and bifurcations of exotic wakes. Based on numerical simulations of the flow, the topology of the wake will be analyzed with methods from the theory of nonlinear dynamical systems. The project will comprise development of a simulation code, topological post-processing tools, as well as extensions of existing mathematical concepts needed to describe the topology of vortex flows. The project will be conducted in close collaboration with researchers at Manchester University, UK.   

Candidates must have a master’s degree in either mathematics, applied mathematics, physics or mechanical engineering, or equivalent academic qualifications. Preference will be given to candidates who can document qualifications in nonlinear dynamics and scientific computing and in addition has a background in fluid mechanics. Furthermore, good command of the English language is essential.   

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in the DTU Compute PhD School Programme. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.   

The assessment of the applicants will be made by Professor Morten Brøns.  

We offer
We offer an interesting and challenging job in an international environment focusing on education, research, scientific advice and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.

Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.
