  1. 1. PIV measurements of rotational flow in a porous medium : A masters thesis in fluid dynamics and experimental mechanics

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Björn Skarman; [2022]
    Keywords : PIV; particle image velocimetry; velocimetry; refractive index matching; porous medium; rotational flow;

    Abstract : The purpose of this work is to test the feasibility of using particle image velocimetry(PIV) for measurements of flow through a porous medium, more specifically in this casea rotating bed reactor S3. The results from experiments preformed can then be usedto validate and improve computational fluid dynamics models. READ MORE

  3. 2. Enabling high-fidelity measurements of turbulent boundary layer flow over wing sections in the MTL wind tunnel.

    University essay from KTH/Mekanik

    Author : Fermin Mallor; [2019]
    Keywords : Fluid mechanics; aerodynamics; turbulence; RANS; wind-tunnel experiments; insert design; Strömningsmekanik; aerodynamik; turbulens; RANS; vindtunnel experiment; inlaga designen;

    Abstract : A reinforced fiber-glass model of a NACA 4412 wing profile is designed and set-up in the Minimum Turbulence Level (MTL) wind tunnel facility at KTH. The model has 65 pressure taps orifices, and the set-up includes two mounting panels designed to allow for particle image velocimetry (PIV) and hot wire anemometry (HWA) measurements of the boundary layer (to be performed in a future campaign).

  4. 3. Flow Separation Control Utilizing Plasma Actuators

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Stefan Nilsson; [2018]
    Keywords : plasma actuator; flow separation control; fluid dynamics; aerodynamics; aerospace engineering; plasma physics;

    Abstract : The goal of this thesis was to both theoretically and experimentally show the effect of a plasma actuator for flow separation control.  In the theoretical part a solver was implemented in MATLAB code, to solve the governing equations describing the plasma actuator. READ MORE

  5. 4. Experimental study of a flow into an engine cylinder using PIV

    University essay from KTH/Mekanik

    Author : Alessandro Davario; Vincenzo Di Lella; [2017]
    Keywords : Swirl motion; Tumble motion; PIV; intake stroke; Diesel engine.;

    Abstract : This degree project is focused on the study of the tumble and the swirlmotions, which develop during the intake stroke, inside a cylinder of a Dieselengine.Nowadays, the reduction of fuel consumption and emissions is a primaryaspect for automotive companies, including Scania.

  6. 5. Validation of CFD simulation with PIV measurements for Open Rotor Noise Predictions

    University essay from KTH/Mekanik

    Author : THOMAS JEAN BERNARD POMMIER; [2015]
    Keywords : ;

    Abstract : CROR means Contra--‐Rotating Open Rotor. Its efficiency is better than usual in aeronautics thanks to its geometry (open rotor and thus high bypass ratio) but also by adding a second rotor. Indeed it enables to recover the swirl loss of the first rotor. However, this engine is rarely used today in civil aviation for acoustic reasons. READ MORE
