PhD in Experimental Streaming Mechanics and Complex Films

Project description Doctoral studies subject: Technical Mechanics FLOW is a strong research environment with researchers who conduct both basic and applied research in fluid mechanics at the Department of Engineering Mechanics.

We are looking for a doctoral student with an experimental focus in fluid mechanics for the group Fluids and Surfaces within FLOW. The service offers an exciting opportunity for a highly motivated candidate to contribute to a research project at the forefront, funded by the Swedish Research Council (VR).

The project aims to increase understanding of how complex films, including biological and live films, interact with surrounding fluid flows. Such films occur to a large extent both in nature and in technical applications, from mucus in the lungs to biofilms on medical devices and ship hulls. When the films are exposed to shearing and potentially time-variing flows, they can be deformed into complex shapes, exhibit unusual material properties and develop over time. As a result, they are a dynamic and continuously changing channel for the flow. At the same time, films affect the overall flow and can change friction resistance as well as transport and exchange of different substances.

Despite their importance, the interplay between complex films and fluid flows is still poorly understood. This limits our ability to predict and control these systems and poses significant challenges in medical, industrial and geophysical applications.

In this project, the doctoral student will work with and further develop a unique experimental platform for studying complex films under controlled but at the same time complex flow conditions. The experimental work will be complemented by continuum modelling of complex materials, data-driven methods and computational fluid mechanics (CFD).

Tutorial: Shervin Bagheri is proposed to supervise the doctoral student. The decision is made at admission Admission requirements To be admitted to doctoral studies (chapter 7 39 § Higher Education Ordinance) the applicant must have basic eligibility: completed a degree at advanced level, or completed the course requirements of at least 240 credits, of which at least 60 credits at advanced level, or in some other way within or outside the country acquired mainly equivalent knowledge.

In addition to the above, there is also a mandatory requirement in English equivalent to English B/6.

Selection To succeed in your doctoral studies at KTH, you need to be targeted and persistent in your work. In the selection of the applicants, the ability to: independently drive their work forward, be able to collaborate with others, have a professional approach, analyze and work with complex issues and experience of experimental fluid mechanics is assessed.

After the eligibility requirements, great emphasis will be placed on personal characteristics.

Goal degree: Doctoral degree Information about admission and employment Only those admitted to doctoral studies may be employed as a doctoral student. The total period of employment may not exceed that corresponding to full-time doctoral education for four years. An employed doctoral student can to a limited extent (maximum 20 %) perform certain tasks within e.g. education and administration. A new position as a doctoral student is valid for a maximum of one year, the employment may then be renewed for a maximum of two years at a time. In studies to be completed with a licentiate degree, the total duration of employment may not exceed that corresponding to full-time doctoral education for two years.

As a doctoral student, you will receive KTH's employment benefits and have a monthly salary according to KTH's agreement for doctoral salaries. Read more about Doctoral Studies at KTH Royal Institute of Technology ( KTH Royal Institute of Technology).
