  2. 1. Computational fluid-dynamics investigations of vortex generators for flow-separation control

    Author : Florian von Stillfried; Arne Johansson; Stefan Wallin; Jonathan Morrison; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow-separation control; vane vortex generator; vortex generator jet; zero-pressure-gradient turbulent boundary layer; adverse-pressure-gradient turbulent boundary layer; statistical modelling; turbulence; Reynolds stress- transport model; computational fluid dynamics;

    Abstract : Many flow cases in fluid dynamics face undesirable flow separation due to ad-verse pressure gradients on wall boundaries. This occurs, for example, due togeometrical reasons as in a highly curved turbine-inlet duct or on flow-controlsurfaces such as wing trailing-edge flaps within a certain angle-of-attack range.

  4. 2. Computational studies of passive vortex generators for flow control

    Author : Florian von Stillfried; Arne Johansson; Stefan Wallin; Sinisa Krajnovic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passive flow control; vortex generator; statistical modelling; turbulence; separation prevention; flat plate; diffuser; high-lift design; airfoil; Fluid mechanics; Strömningsmekanik;

    Abstract : Many flow cases in fluid dynamics face undesirable flow separation due torising static pressure on wall boundaries. This occurs e.g. due to geometry as ina highly curved turbine inlet duct or e. READ MORE

  5. 3. Benchmark Simulation Model for Integrated Urban Wastewater Systems : Model Development and Control Strategy Evaluation

    Author : Ramesh Saagi; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Benchmark Simulation Model; Integrated control strategies; Integrated modelling; River water quality;

    Abstract : The integrated urban wastewater system (UWS) consists of different sections that are interconnected. These include: i) catchment; ii) sewer network; iii) wastewater treatment plant (WWTP); and finally, iv) receiving water system. Traditionally, these sections are operated and evaluated individually.

  6. 4. Computer Simulation of the Neural Control of Locomotion in the Cat

    Author : Nalin Harischandra; Örjan Ekeberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Locomotion; Computer simulation; Central pattern generator; Muscle activation; Linear transfer functions; Sensory feedback; Neural control; Computer science; Datavetenskap;

    Abstract : Locomotion is one of the most important behaviours and requires interaction between sensors at various levels of the nervous system and the limb muscles of an animal. The basic neural rhythm for locomotion in mammals has been shown to arise from local neural networks residing in the spinal cord and these networks are known as central pattern generators (CPGs).

  7. 5. A Theoretical Study of Carbon Nanotubes in Electronic Packaging Applications

    Author : Zhili Hu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; simulation; thermal interface material; continuum; electronic packaging; MDs; CNT;

    Abstract : The continuous decrease in size of transistors has allowed more components to be integrated in a single unit area and brings a range of opportunities as well as problems to the electronic packaging industry. To meet these challenges, the introduction of Carbon Nanotubes (CNT), which display a series of extraordinary properties, have attracted great interest. READ MORE
