  1. 1. PIV in Practice

    Author : Torbjörn Green; Luleå tekniska universitet; []

    Abstract : Experimental fluid mechanics has for a long time been used to visualize flow phenomenonqualitatively. Traditionally, visualization has been done with dye or tracer particle dueto their ability to follow the flow pattern well. READ MORE

  2. 2. PIV measurements in a separating turbulent APG boundary layer

    Author : Kristian Angele; KTH; []
    Keywords : Adverse pressure gradient APG ; Turbulent; Boundary layer; Separation; PIV;

    Abstract : .... READ MORE

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

    Author : Timmy Sigfrids; KTH; []
    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

  4. 4. Experimental and computational studies of turbulent separating internal flows

    Author : Olle Törnblom; Arne V. Johansson; Michel Stanislas; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; turbulence; flow separation; turbulence modelling; asymmetric diffuser; boundary layer; PIV; vortex generator; separation control; Fluid mechanics; Strömningsmekanik;

    Abstract : The separating turbulent flow in a plane asymmetric diffuser with 8.5 degrees opening angle is investigated experimentally and computationally. The considered flow case is suitable for fundamental studies of separation, separation control and turbulence modelling. READ MORE

  5. 5. Experimental Studies of Turbulent Mixing in Impinging Jets

    Author : Rong Ding; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LDV; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; PIV LIF; TR- LIF; TR- PIV; perturbed- and swirling- impinging jets; passive control; frequency spectrum; turbulent fluxes; impinging jets; turbulent mixing;

    Abstract : This thesis concerns the experimental study of mixing and flow characteristic in turbulent circular impinging jets without and with jet orifice manipulators (i.e. passive-fixed perturbations atthe nozzle exit), without and with swirl. READ MORE
