Project description

Third-cycle subject: Fluid mechanics

The goal of this project is to use computational-fluid-dynamics (CFD) methods and experiments for the analysis of turbulent flows in urban environments. 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 the geometry and inflow conditions on the physics, and the pollutant concentration in the city. We are also interested in using deep-learning methods for non-intrusive sensing, so as to create detailed maps of velocity and pollutant concentration in the city from sparse measurements.

The doctoral student will 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) and will become part of the excellent research environment FLOW (www. flow.kth.se). This project is part of an EU Doctoral Network, so research stays will be planned with other partners, including Polytechnic University of Madrid, Barcelona Supercomputing Center, Université Libre de Brussels, University of Bristol and a number of industrial partners.

Supervision: The doctoral students will be supervised by Ricardo Vinuesa, Hossein Azizpour and Fariya Sharmeen.

What we offer
  • The possibility to study in a dynamic and international research environment in collaboration with industries and prominent universities from all over the world. Read more
  • A workplace with many employee benefits and monthly salary according to KTH's Doctoral student salary agreement.
  • A postgraduate education at an institution that is active and supportive in matters pertaining to working conditions, gender equality and diversity as well as study environment.
  • The researcher will become part of the VinuesaLab research group (www. vinuesalab.com), where he/she will have the possibility to interact with several related projects dealing with large-scale turbulence simulations, deep learning and experiments.
  • Work and study in Stockholm, close to nature and the water.
  • Help to relocate and be settled in Sweden and at KTH.
  • Admission requirements

    To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

  • passed a second cycle degree (for example a master's degree), or
  • completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
  • acquired, in some other way within or outside the country, substantially equivalent knowledge
  • Recruited researchers can be of any nationality and must comply with the following mobility rule: they must not have resided or carried out their main activity (work, studies, etc.) in Sweden for more than 12 months in the 36 months immediately before their recruitment date.
  • A suitable background for this position would be a Master of Science in Computer Science, Physics, Mathematics or Mechanics with a specialization in fluid mechanics, computational methods and/or applied mathematics.

    In addition to the above, there is also a mandatory requirement for English equivalent to English B/6, read more here

    Selection

    In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

  • independently pursue his or her work
  • collaborate with others,
  • have a professional approach and
  • analyse and work with complex issues.
  • After the qualification requirements, great emphasis will be placed on personal competency.

    Target degree: Doctoral degree

    Information regarding admission and employment

    Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.
