  1. 1. Hot wire and PIV studies of transonic turbulent wall-bounded flows

    University dissertation from Stockholm : Mekanik

    Author : Timmy Sigfrids; KTH.; [2003]
    Keywords : fluid mechanics; compressible flow; turbulence; boundary layer; hot-wire anemometry; PIV; shock wave boundary layer interaction; shape factor;

    Abstract : The compressible turbulent boundary layer developing over atwo-dimensional bump which leads to a supersonic pocket with aterminating shock wave has been studied. The measurements havebeen made with hot-wire anemometry and Particle ImageVelocimetry (PIV). 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. 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

  4. 4. Experimental study of turbulent flows through pipe bends

    University dissertation from KTH Royal Institute of Technology

    Author : Athanasia Kalpakli; KTH.; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent flow; swirl; pulsation; pipe bend; hot-wire anemometry; cold-wire anemometry; laser Doppler velocimetry; stereoscopic particle image velocimetry.;

    Abstract : This thesis deals with turbulent flows in 90 degree curved pipes of circular cross-section. The flow cases investigated experimentally are turbulent flow with and without an additional motion, swirling or pulsating, superposed on the primary flow. READ MORE

  5. 5. Experimental study of the rotating-disk boundary-layer flow

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Shintaro Imayama; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; boundary layer; rotating disk; laminar-turbulent transition; convective instability; absolute instability; secondary instability; crossflow instability; hot-wire anemometry.;

    Abstract : Rotating-disk flow has been investigated not only as a simple model of cross flow instability to compare with swept-wing flow but also for industrial flow applications with rotating configurations. However the exact nature of laminar-turbulent transi- tion on the rotating-disk flow is still major problem and further research is required for it to be fully understood, in particular, the laminar-turbulent transition process with absolute instability.
