  1. 1. Flow Measuring Techniques in Steady and Pulsating Compressible Flows

    Detta är en avhandling från Stockholm : KTH

    Författare :Fredrik Laurantzon; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow measuring; compressible flow; steady flow; pulsating flow; hot-wire anemometry; cold-wire anemometry; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik;

    Sammanfattning : This thesis deals with flow measuring techniques applied on steady and pulsatingflows. Specifically, it is focused on gas flows where density changes canbe significant, i.e. compressible flows. LÄS MER

  3. 2. Flow measurements related to gas exchange applications

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Fredrik Laurantzon; KTH.; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow meters; vortex flow meters; compressible flow; pulsating flow; hot-wire anemometry; cold-wire anemometry; time resolved measurements; wavelet analysis;

    Sammanfattning : This thesis deals with flow measuring techniques applied to steady and pulsating gas flows relevant to gas exchange systems for internal combustion engines. Gas flows in such environments are complex, i.e. they are inhomogeneous, three-dimensional, unsteady, non-isothermal and exhibit significant density changes. LÄS MER

  4. 3. Flow Java declarative concurrency for Java

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Frej Drejhammar; KTH.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datorsystem; Datorsystem; TECHNOLOGY Information technology Computer engineering; TEKNIKVETENSKAP Informationsteknik Datorteknik;

    Sammanfattning : This thesis presents the design, implementation, and evaluation of Flow Java, a programming language for the implementation of concurrent programs. Flow Java adds powerful programming abstractions for automatic synchronization of concurrent programs to Java. LÄS MER

  5. 4. Water and Heat Transport in Road Structures Development of Mechanistic Models

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Klas Hansson; Uppsala universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Water flow; Heat flow; Unsaturated flow; Freeze-thaw; Numerical models; Uncertainty analysis; Sensitivity analysis; Roads; Overland flow; Flow patterns; TDR; Water content reflectometer; Calibration; Fractures; Hydrologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi;

    Sammanfattning : The coupled transport of water and heat, involving freezing and thawing, in the road structure and its immediate environment is important to consider for optimal design and maintenance of roads and when assessing solute transport, of e.g. de-icing salt, from roads. LÄS MER

  7. 5. Non-Spherical Particle Interaction in Duct and Jet Flow

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Ammar Hazim; Luleå tekniska universitet.; [2015]
    Nyckelord :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; Engineering mechanics - Fluid mechanics; Teknisk mekanik - Strömningsmekanik; Strömningslära; Fluid Mechanics;

    Sammanfattning : 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. LÄS MER
