1. 1. Design and investigation of a pulsating heat pipe for electronic cooling

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Sulafa Hammad; [2023]
   Nyckelord :Pulsating heat pipes PHP ; Electronic cooling; two phase flow heat transfer; Technology and Engineering;

   Sammanfattning : The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. LÄS MER

3. 2. General Defocus Particle Tracking

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Joakim Anderberg; [2023]
   Nyckelord :General Defocus Particle Tracking; ultrasonic standing waves; microscopy; microchip; single plane particle tracking; levitation; Generel ur-fokus partikel spårning; stående ultraljudsvågor; mikroskopi; mikorchip; enkelplans partikel spårning; levitation;

   Sammanfattning : Three-dimensional particle tracking is a valuable tool in microfluidics for obtaining information about a system. General Defocus Particle Tracking (GDPT) is a straightforward method of 3D particle tracking that only requires a single-camera plane, making it applicable to existing equipment in a laboratory.

4. 3. Improving bright-field images for tracking particles with Defocustracker

   Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Carl Lundin; [2022]
   Nyckelord :Defocustracker; GDPT; particle tracking; bright-field; acoustophoresis; Laplacian of Gaussian; Technology and Engineering;

   Sammanfattning : Acoustophoresis is a cell separation technology where particles or cells are suspended in a fluid container and subject to acoustic standing waves. The standing waves exerts an acoustic radiation force on the particles, pushing them towards the nodal plane. LÄS MER

5. 4. Semi-Automatic Analysis and Visualization of Cardiac 4D Flow CT

   Master-uppsats, Linköpings universitet/Institutionen för hälsa, medicin och vård

   Författare :Anthony van Oosten; [2022]
   Nyckelord :4D CT; CT; 4D flow; Flow Component Analysis; Singular value decomposition; left atrial appendage; LAA; CFD; 3 chamber view; computed tomography; maximum outflow velocity; volume rendered CT; semi-automatic; visualization; flow visualization; cardiac views; semi-automatic analysis; semi-automatic visualization; visualization of 4D flow;

   Sammanfattning : The data obtained from computational fluid dynamics (CFD) simulations of blood flow in the heart is plentiful, and processing this data takes time and the procedure for that is not straightforward. This project aims to develop a tool that can semi-automatically process CFD simulation data, which is based on 4D flow computed tomography (CT) data, with minimal user input. LÄS MER

7. 5. Simulation strategies for improved contamination modeling of liquid dynamics on automotive surfaces

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Thisal Mandula Sugathapala; Twan Bakker; [2022]
   Nyckelord :Volume of Fluid; Contamination modeling; Blended Kistler model; Dynamic contact angle models; Exterior water management; Light-induced fluorescence imaging; Multiphase flows; Surface flows; Computational fluid dynamics; Sensor soiling;

   Sammanfattning : A significant level of research is currently being carried out in the development of driver support systems as they are expected to play a key role in minimizing road vehicle accidents and creating a safe driving environment under harsh weather conditions. However, the performance of some components used by existing driver support systems like LIDAR and visual cameras are affected by extreme weather conditions such as heavy rain fall and snow. LÄS MER
