  2. 1. Acoustic separation of submicron particles in gaseous flows

    Author : Ramin Imani Jajarmi; Laszlo Fuchs; Etienne Robert; Klas Engvall; Martin Wiklund; KTH; []
    Keywords : Acoustic; submicron particles; gaseous flows; separation; Engineering Mechanics; Teknisk mekanik;

    Abstract : The separation of submicron particles suspended in gaseous flows is a problem of great importance and is the subject of sustained research efforts. This is motivated by several challenges presented by modern science and technology requiring high separation efficiencies for submicron particles.

  4. 2. Supersonic flow separation with application to rocket engine nozzles

    Author : Jan Östlund; KTH; []
    Keywords : turbulent; boundary layer; shock wave; interaction; overexpanded; rocket nozzle; flow separation; control; side-load; experiments; models; review;

    Abstract : The increasing demand for higher performance in rocketlaunchers promotes the development of nozzles with higherperformance, which basically is achieved by increasing theexpansion ratio. However, this may lead to flow separation andensuing instationary, asymmetric forces, so-called side-loads,which may present life-limiting constraints on both the nozzleitself and other engine components.

  5. 3. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer

    Author : Erik Olof Nilsson; Anna Rutgersson; Harm Jonker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Waves; Growing sea; Swell; Marine boundary layer; Air-sea interaction; Mixing; Momentum flux; Wind stress; Flux attenuation; Sensor separation; Large eddy simulation; Multiresolution analysis; Coupling; Wave model; Climate model; Wave age; Meteorology; Meteorologi;

    Abstract : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. READ MORE

  6. 4. Acoustic Standing Wave Manipulation of Particles and Cells in Microfluidic Chips

    Author : Andreas Lenshof; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic particle manipulation; separation; ultrasound; cell handling; particle handling; lab on a chip; Microsystem technology; microfluidics; standing waves;

    Abstract : The rise of MEMS and µTAS techniques has created a whole new family of microfluidic devices for a wide range of chemical and biomedical analyses to be performed on small Lab-on-a-chip platforms. The operations often include small samples of particle or cell suspensions on which separation, mixing, trapping or sorting is performed. READ MORE
