KTH Royal Institute of Technology, School of Engineering Sciences

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 architecture, industrial management, urban planning, history and philosophy.

The School of Engineering Sciences carries out a wide range of research at the international front line, from fundamental disciplines such as Physics and Mathematics, to Engineering Mechanics with applications such as Aeronautics and Vehicle Engineering. We also offer university degree programs in Engineering Physics, Vehicle Engineering, and 'Open entrance', as well as a number of international masters programmes.

Job description

The postdoctor will work in the project PROMETHEUS (Plasma drag ReductiOn METHodology for effective Energy Usage) which aims towards reducing drag on heavy duty vehicles by using plasma actuators to control separation on the front corner (A-pillar) especially under yawed conditions. The first part of the project will be a fundamental study of the interaction of the plasma actuator wall jet (electric wind) with the incoming boundary layer when the actuators are used as streamwise vortex generators. Various geometrical parameters of the actuators (streamwise length and spanwise spacing) should be investigated to be able to optimize plasma actuator arrays as well as to investigate whether a pulsed mode operation with a suitable duty cycle and pulse frequency could be advantageous. In a second part of the project the methodology will be applied to a generic truck geometry and direct drag measurements should be performed in a wind tunnel. Postdoctoral position for one year, can be extended with a second year. 

Qualifications

We are looking for a candidate with a doctoral education (completed in the last three years or soon to be completed) in experimental aerodynamics/fluid dynamics with documented experience of using plasma actuators for flow control. Experience of using PIV and stereo PIV is also important to qualify for this position. Good knowledge to communicate in English orally and in writing is required.
