  2. 21. High-speed 3D imaging of liquid jets, surfaces and respiratory droplets

    Author : Adrian Roth; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Laser Induced Fluorescence; Volumetric imaging; Structured Illumination; 3D Reconstruction; Stereoscopy; 3D Particle Tracking Velocimetry; COVID­19; sprays; respiratory droplets; Fysicumarkivet A:2023:Roth;

    Abstract : Sprays are commonly found in, among other, combustion, agriculture and food processing. For each of these applications, the understanding of spray liquid dynamics is crucial for optimization of efficiency, accuracy, and robustness of the spray­-system in use. READ MORE

  4. 22. Experimental study of bubble dynamics and transport

    Author : Gunilla Andrée; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; Particle Streak Photography; Shadowgraph; Particle Image Velocimetry; Bubble dynamics; bubble transport;

    Abstract : The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. READ MORE

  5. 23. Particle-Induced Phase Separation in Aqueous Solutions containing Colloidal Particles and Adsorbing Polymers

    Author : Martin Olsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; theoretical calculations; particle-induced phase separation; phase behaviour; surfactant; colloidal particles; adsorbing polymer;

    Abstract : The influence of added colloidal particles on the phase behaviour of a polymer solution was investigated. Binary, quasi-binary and mixed polymer solutions were used in the study, where at least one of the polymers had an affinity for the surfaces of the colloidal particles. READ MORE

  6. 24. Estimating particle size distributions based on machine vision

    Author : Tobias Andersson; Anthony Maeder; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : This thesis contributes to the field of machine vision and the theory of the sampling of particulate material on conveyor belts. The objective is to address sources of error relevant to surface-analysis techniques when estimating the sieve-size distribution of particulate material using machine vision. READ MORE

  7. 25. Smoothed Particle Hydrodynamic of Hydraulic Jumps in Spillways

    Author : Patrick Jonsson; Peter Stansby; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : This thesis focus on the complex natural phenomena of hydraulic jumps using the numerical method Smoothed Particle Hydrodynamics (SPH). A hydraulic jump is highly turbulent and associated with turbulent energy dissipation, air entrainment, surface waves and spray and strong dissipative processes. READ MORE
