  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

  2. 2. 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

  3. 3. Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Amir Sattari; Högskolan i Gävle.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle Image Velocimetry PIV ; experimental study; structured light 3D scanning system; ventilation; varying flow rate; room model; wall-mounted radiator; air; water; flow; Particle Image Velocimetry PIV ; experimentell studie; scanningsystem för strukturerat 3D-ljus; ventilation; varierande tilluftsflöde; rumsmodell; väggmonterad radiator; Engineering Mechanics; Teknisk mekanik; Byggvetenskap; Civil and Architectural Engineering; Energy Technology; Energiteknik;

    Abstract : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. READ MORE

  5. 5. Blood Flow variations in Large Arteries due to non-Newtonian rheology

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Stevin van Wyk; KTH.; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

    Abstract : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. READ MORE
