School of Engineering Sciences at KTH

Project description

Third-cycle subject: Engineering Mechanics

This project is part of LUBFLOW, which has the objective to develop a fundamental understanding of lubricant-infused surfaces in fluid flows, which could have significant implications for various technological applications.

We are now seeking a PhD student in computational fluid mechanics.

A lubricant-infused surface (LIS) is a structured surface infused with a viscous liquid layer. These slippery surfaces are partially inspired by the carnivorous Nepenthes pitcher plant. LISs have shown great promise for reducing fluid friction, preventing biofouling and increasing heat transfer in fluid flows. However, the behaviour of LISs in realistic flow environments is very difficult to predict. LUBFLOW will therefore investigate LISs in fluid flows that include turbulence, surfactants and bacteria. This could lead to better control of fluid flows and broad technological advancements.

Main purpose of the computational work that will carried out in this project are:

  • Discover new physics and functions of liquid-infused surfaces in laminar and turbulent flows including effects of surfactants, interfacial phenomena, particle dynamics, thermocapillary etc.
  • Interact and contribute to physical understanding of experimental observations related to other LUBFLOW projects.

This project also allows for serendipitous tasks in international collaboration. We have extensive experience with computational fluid mechanics both within the research group and division of fluid mechanics at KTH. We also have access to large computing allocations in Sweden. 

This position provides an exciting opportunity for talented and motivated researchers to work on a cutting-edge research project.

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

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


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
  • Experience in numerical calculations, computational techniques or fluid mechanics are very valuable

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. In the case of studies that are to be completed with a licentiate degree, the total period of employment may not be longer than what corresponds to full-time doctoral education for two years.
