  1. 1. Comparison of Particle Tracking and ADCP Including Construction of the Rating Curve at Islandsfallet

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Rasmus Møller Jess; Fredrik Norstedt; [2023]
    Keywords : Rating Curve; Islandsfallet; Fyrisån; Particle Tracking; LSPIV; Fudaa; Hydrology;

    Abstract : The objective of this study is to compare Large-Scale Particle Image Velocimetry (LSPIV) to conventional methods for measuring discharge. Furthermore, to use the discharge data to create a rating curve at Islandsfallet in Uppsala. To measure discharge, on-site measurements have conventionally been done. READ MORE

  3. 2. Ultrasound Imaging Velocimetry using Polyvinyl Alcohol Shelled Microbubbles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ida Johansson; [2022]
    Keywords : Ultrasound imaging velocimetry; ultrasound contrast agents; polyvinyl alcohol; microbubbles; echo particle image velocimetry; Ultrasound imaging velocimetry; ultraljudskontrastmedel; polyvinylalkohol; mikrobubblor; echo particle image velocimetry;

    Abstract : Current research within the field of ultrasound contrast agents (UCAs) aims at developing capsules which are not only acoustically active, but also have a chemically modifiable surface. This enables use in new areas, including targeted drug delivery and theranostics. READ MORE

  4. 3. 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

  5. 4. In-vivo imaging of root growth in response to localized mechanical stress

    University essay from SLU/Dept. of Soil and Environment

    Author : Leah Eitelberg; [2022]
    Keywords : kinematics analysis; time-lapse imaging; root growth rate; root curvature; soil heterogenety; local mechanical stress;

    Abstract : By taking up nutrients and water, root growth has an important influence on plant growth and productivity. Thereby, root growth is influenced by its surrounding soil conditions, which vary spatially even on a small scale. Hence, different parts of the root system are exposed to different penetration resistances in the soil. READ MORE

  6. 5. 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).
