  2. 1. Non-Spherical Particle Interaction in Duct and Jet Flow

    Author : Ammar Hazim; Matthias Mandø; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid-gas flow; turbulence modulation; duct flow; coaxial jets flow; swirl jet flow; active flow control; synthetics jet; biomass powder; non-spherical particles; PIV measurement; Strömningslära; Fluid Mechanics;

    Abstract : Wood waste is the most popular biomass recourse for many nations. Burned wood can, direct or indirect, release one of the greenhouse gases, carbon dioxide. The process can still be seen as a renewable source of energy since replanting of the trees and crops are consuming nearly the same amount of carbon dioxide through photosynthesis. READ MORE

  4. 2. Choreographing Flow : A Study in Concrete Deposition

    Author : Helena Westerlind; Hélèna Frichot; Marcelyn Gow; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Architectural Technology; Arkitekturteknik;

    Abstract : The traditional use of concrete in architecture is fundamentally conditioned by the inverse relationship that exists between material and formwork. When poured into a mold, a homogenous mixture takes the shape of its container. More detailed adjustment of the structure of concrete, however, is not possible. READ MORE

  5. 3. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

    Author : Annica Lindqvist-Östblom; Linköpings universitet; []
    Keywords : flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

    Abstract : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. READ MORE

  6. 4. Interaction of flows with slender structures and liquid-infused surfaces

    Author : Johan Sundin; Shervin Bagheri; Daniel Chung; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow-structure interactions; flow control; turbulent boundary layers; soft sensors; drag reduction; capillary waves; surfactants; Marangoni stress; mixing enhancement; Engineering Mechanics; Teknisk mekanik;

    Abstract : Surface textures and protrusions can be used to control or gain information about a flow. We investigate the solid-flow interaction of filamentous structures and liquid-infused surfaces (LIS). Both filamentous structures and LIS are used by organisms and can be exploited in technical applications. READ MORE

  7. 5. Flow structures in solid-liquid suspensions in mixing and confined jets

    Author : Matthias Eng; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lomb algorithm; macro-instabilities; stirred tank; integral length scale; solid-liquid; confined jet; LDV; parcticle flow; jet instability;

    Abstract : This thesis investigates the influence of solid particles on different liquid flow systems.Large-scale periodic fluctuations such as macro instability (MI) phenomena in a mixingvessel and jet flows in a confined jet were experimentally analyzed by means of LDV. Theinfluences of different sized (0.5mm-2mm) glass particles (0%vol - 6. READ MORE
