  1. 16. Hydrodynamic flow for deterministic sorting of cell-membrane components

    Author : Björn Johansson Fast; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; Diffusion; Microfluidics; Native membrane vesicles; Single particle tracking; Protein enrichment; Hydrodynamic forces; Supported lipid bilayer; Size determination;

    Abstract : The biological membrane, an amphiphilic structure that is the barrier between the cell interior and exterior, is one of the vital building blocks of all cells. Not only does it define the outer boundaries of the cell, it also carries important biological function by virtue of the proteins and other molecules that constitute the membrane, the function of which is in turn intimately coupled to their association with the lipid-based membrane.

    Abstract : Cavitation is a problem in many hydroelectric power plants since it can cause adverse effects on performance and damage to nearby solid surfaces. The concerns of this thesis are the numerical aspects of flow simulations in cavitating hydraulic turbines which contain several difficulties: turbulent and complex flows, steady and moving parts of the geometry, bubble transport and cavitation development.

  3. 18. 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. 19. Computational methods for microfluidics

    Author : Ludvig af Klinteberg; Anna-Karin Tornberg; Peter Hansbo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is concerned with computational methods for fluid flows on the microscale, also known as microfluidics. This is motivated by current research in biological physics and miniaturization technology, where there is a need to understand complex flows involving microscale structures. Numerical simulations are an important tool for doing this. READ MORE

  5. 20. Measurement and evaluation of near-field spray kinematics for nozzles with asymmetrical inlet geometries

    Author : Mohammad Nikouei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nozzle Geometry; Spray Dynamics; Spray Velocity; Diesel Spray; Ballistic Imaging;

    Abstract : In diesel engines, fuel injection parameters have a commanding effect on mixing and combustion quality. This research aims to enhance the fundamental knowledge of fuel sprays and their primary break-up. In addition, this research provides statistical data to validate simulation models and improve the prediction accuracy in mixing and combustion. READ MORE
