KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as in architecture, industrial management, urban planning, history and philosophy.
In the present announcement we aim at using computational fluid dynamics (CFD) to characterize the flow in several moderately complex geometries, including the (laminar, transitional and turbulent) flow through bent and coiled pipes, pressure-gradient turbulent boundary layers with different history effects and the turbulent flow around wingtips and three-dimensional wings. To this end, high-order spectral methods will be employed to perform both well-resolved large-eddy simulations and direct numerical simulations, in order to assess the influence of pressure gradient, curvature and three-dimensionality in the dynamics of the flow. Stability analyses will be performed in bent pipes to further understand the swirl-switching phenomenon and to compute for the first time the stability diagram for helical pipe flow. Flow statistics, spectral and structural analyses will be used in the turbulent boundary layers with pressure gradients and around wings. The students will become part of the Virtual Wind-Tunnel Programme (VWTP) at the Linné FLOW Centre (www.flow.kth.se), where they will have the possibility to interact with several related projects dealing with large-scale simulations and corresponding experiments, and will also have access to the multi-peta scale supercomputing facilities available at KTH, in conjunction with the Swedish e-Science Research Centre (SeRC, www.e-science.se).
The employment is four years with a possibility of maximum up to five years. Up to 20 percent department duties are included in the employment. We are looking for up to three candidates regarding this position.
A suitable background for this position would be a Master of Science in Physics, Mathematics, Mechanics or Electrical Engineering with a specialization in fluid mechanics, computational methods and/or applied mathematics. In addition to the traditional academic merits, a relevant degree project, international experience, and language skills are regarded as advantageous qualifications.
Applicants must be strongly motivated for doctoral studies, possess the ability to work independently and perform critical analysis as well as possessing good levels of cooperative and communicative abilities.
