  2. 31. Lagrangian Particles in Turbulence and Complex Geometries

    Author : Azad Noorani; Philipp Schlatter; Johan Revstedt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direct numerical simulation; wall turbulence; secondary motion; Teknisk mekanik; Engineering Mechanics;

    Abstract : Wall-dominated turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the  arrier and the dispersed phase is elevated to a higher level introducing geometrical complexities such as curved walls. READ MORE

  5. 33. MULTICOMPONENT SPRAY-TURBULENCE INTERACTION

    Author : Vignesh Pandian Muthuramalingam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasoline diesel blend; CFD; multicomponent fuel sprays; ethanol iso-octane blend; Stochastic Blob and Bubble VSB2 spray model; direct injection engines;

    Abstract : Blended fuels are gaining importance in automotive industry owing to stringent legislations for emissions. It is important to understand the fuel spray formed as a consequence of injecting blended fuels into the engine (for direct injection engines) and also the influence of fuel spray on combustion properties.

  6. 34. Turbulence-resolving simulations for engineering applications

    Author : Bastian Nebenführ; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; Aeroacoustics; Forest canopy; Airframe noise; hybrid RANS LES; Turbulence-resolving simulation; Wind-turbine fatigue loads; Wind power;

    Abstract : Most fluid flows of industrial interest are turbulent and their accurate representation may be of vital importance for the design process of new products. To date, steady RANS methods are usually employed for the simulation of turbulent flows of everyday engineering problems. READ MORE

  7. 35. Extending MRI to the Quantification of Turbulence Intensity

    Author : Petter Dyverfeldt; Tino Ebbers; Krishna Nayak; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence intensity; cardiovascular disease; blood flow; hemodynamics; magnetic resonance imaging; generalized phase-contrast MRI; turbulent flow; Medical technology; Medicinsk teknik; Fluid mechanics; Strömningsmekanik;

    Abstract : In cardiovascular medicine, the assessment of blood flow is fundamental to the understanding and detection of disease. Many pharmaceutical, interventional, and surgical treatments impact the flow. The primary purpose of the cardiovascular system is to drive, control and maintain blood flow to all parts of the body.
