2. 1. Flow-induced Surface Defects and Ageing Behaviour of Injection-moulded Polymers

   Author : Giovanna Iannuzzi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PP; surface defects; flow marks tiger stripes ; ageing; Injection moulding; ABS; rheological properties; degradation; surface topography; discolouration;

   Abstract : Injection moulding is one of the most commonly used manufacturing methods for the production of polymer-based components such as car bumpers and other automotive details. The surface appearance of these products is of great importance since it is directly connected to the perceived quality. READ MORE

4. 2. Numerical Study of Fluid-Structure Interaction with Application to Oscillating Cylinders

   Author : Mikhail Lazarkov; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lock-in.; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; synchronization; flow-induced vibration; LES; Volume of Solid method; Virtual Boundary method; vortex-shedding; confined cylinder; Fluid-structure interaction; wake;

   Abstract : The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. READ MORE

5. 3. Study of the flow-induced structure and anisotropy in lyotropic liquid crystals for hierarchical composites

   Author : Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; Lyotropic liquid crystals; SAXS; Hierarchical materials.; 3D printing; Rheology; Microfluidics; Birefringence microscopy;

   Abstract : Controlling the micro and nanostructure of materials is highly beneficial in order to tailor their physical properties. Extrusion-based 3D printing is a promising tool to produce hierarchical structures with controlled architecture. READ MORE

6. 4. Dynamic Modelling of Physical Processes in Magmatic Systems: Dyke Emplacement and Flow-Induced Crystal Rotations

   Author : Rémi Vachon; Christoph F. Hieronymus; Janine Kavanagh; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical solutions; elasticity and anelesticity; fracturing; magmatic plumbing system; sheet-like intrusions; rheology of the crust; physics of magma; solid mechanics; fluid flow; crystal rotation;

   Abstract : The main motivation for this thesis is to develop and improve numerical tools and methods that help further our comprehension of the volcanic plumbing system and its dynamics.The commonly used standard elastic model predicts solutions of dyke shape, thickness, over-pressure and fracturing criteria that do not always fit natural observations.

7. 5. Exploring the nonlinear rheological behavior and optical properties of cellulose nanocrystal suspensions

   Author : Sylwia Wojno; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; rheology; self-assembly.; rheo-PLI; nonlinear oscillatory shear; FTRheology; Cellulose nanocrystals;

   Abstract : Cellulose nanocrystals (CNCs), with their versatile properties, offer immense potential in a range of applications, whether used independently or as sustainable reinforcements in polymers. They also find utility as renewable rheology modifiers in industries such as cosmetics, paints, and foods, where precise control over rheological characteristics is crucial for factors like product stability, prevention of splattering, and efficient processing and transportation.
