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

    University dissertation from Stockholm : KTH

    Author : Fredrik Laurantzon; KTH.; [2010]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Flow measurements related to gas exchange applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Fredrik Laurantzon; KTH.; KTH.; [2012]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Turbulence modeling of compressible flows with large density variation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Igor Grigoriev; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; DRSM; EARSM; active scalar; compressible flow; reacting flow; supercritical flow; Teknisk mekanik; Engineering Mechanics;

    Abstract : In this study we highlight the influence of mean dilatation and mean density gradient on the Reynolds stress modeling of compressible, heat-releasing and supercritical turbulent flows.Firstly, the modeling of the rapid pressure-strain correlation has been extended to self-consistently account for the influence of mean dilatation.

  5. 5. Large Eddy Simulation of Turbulent Compressible Jets

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Bernhard Semlitsch; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressible Flow; Large Eddy Simulation; Acoustic Noise Generation; Near-field Acoustics; Flow Control; Optimization; Modal Flow Decomposition; Teknisk mekanik; Engineering Mechanics;

    Abstract : Acoustic noise pollution is an environmental aggressor in everyday life. Aero- dynamically generated noise annoys and was linked with health issues. It may be caused by high-speed turbulent free flows (e.g. READ MORE
