A blueprint for future flow research

This research programme aims at utilizing new computational possibilities, hand-in-hand with new key physical experiments, to outline a blueprint for future flow research.

Emphasis is put on control and optimization of flow systems, with the objective of utilizing methods and understanding gained in sensitivity analysis, optimization methods and control theory in boundary layer flows, to obtain drag reduction on bodies, increased lift on wings, increased propulsion efficiency, heat- and mass-transfer reduction or enhancement, control of combustion instabilities, and control of aeroacoustic pressure fluctuations.

Emphasis is also put on flow physics modeling, where we address critical aspects of modeling in order to improve necessary simulation tools. The programme encompasses simulation and modeling of flow instabilities, flow separation as well as turbulence, but also attacks areas such as simulation and modeling of combustion, disturbance growth in the mesoscales of the atmosphere and enhancement of mixing and particle movement in microfluids.

The research environment consists of the world leading fluid mechanics research group at KTH Mechanics and researchers from the MWL laboratory for technical acoustics and the KTH numerical analysis group.

ACCESS – Autonomic Complex Communication nEtworks, Signals, and Systems

It is a networked world: People communicate independent of distance and time; systems communicate with systems as connectivity becomes a natural feature of any electronic device. This research programme aims at developing fundamental understanding and engineering principles for designing self-managed and scalable communication networks in which applications may share real-time information and cooperate in an efficient, affordable, and reliable manner.

Communication networks are vital infrastructures in our society and the basis of more and more services that we take for granted; from connectivity of personal devices in the home and car to global communication and positioning via satellite systems.

At the core of these systems are some fundamental technical issues: they must be designed to carry out the intended functions; the systems must perform efficiently and predictably; they must be manageable, controllable, and upgradeable and they must be reliable to the point of being infallible.

The project is formulated by constellation with expertise in complexity, communications, optimization and system theory; signal, speech and image processing; formal methods, communication networks and automatic control.

ACCESS has the competence to develop new methods and to determine fundamental limitations for the design and evaluation of communication systems and architectures, as well as to actually design system critical components that address challenges in terms of reliability and scalability.
