11. Powder Bed Structure and Imbibition - A Study of Spray Dried Dairy Powders
Sammanfattning : The formation of lumps during powder dissolution is undesirable in most cases. In a world where the use of dry products is increasing, incomplete powder dissolution and lump formation can for instance affect the color of a paint or the nutritional content of baby food. LÄS MER
12. Extended Computational Module for Tractive Effort at Rolling and Spinning Point Contacts
Sammanfattning : One category of mechanical systems that contains power-transferring point contacts is traction drive variators. These variators can be used in different concepts for Continuously Variable Transmissions (CVTs) and in vehicle applications, in order to achieve optimum engine operating conditions leading to improved driveability, reduced fuel consumption and an increase in overall vehicle performance.

13. Cultivating Mechanical Sympathy : Making meaning with ambiguous machines
Sammanfattning : Moving with a drone can be a captivating and reflective experience. A drone can easily grab my attention, yet its hold is distinctly different to a screen where my body goes missing and my eyes are held captive. Instead, my body feels alive and present. As if every part of it is playing a crucial role in keeping the drone in the air. LÄS MER
14. Modelling and Simulation of Reactor Pressure Vessel Failure during Severe Accidents
Sammanfattning : This thesis aims at the development of new coupling approaches and new models for the thermo-fluid-structure coupling problem of reactor pressure vessel (RPV) failure during severe accidents and related physical phenomena. The thesis work consists of five parts: (i) development of a three-stage creep model for RPV steel 16MND5, (ii) development of a thermo-fluid-structure coupling approach for RPV failure analysis, (iii) performance comparison of the new approach that uses volume loads mapping (VLM) for data transfer with the previous approach that uses surface loads mapping (SLM), (iv) development of a lumped-parameter code for quick estimate of transient melt pool heat transfer, and (v) development of a hybrid coupling approach for efficient analysis of RPV failure.

15. Dissolution of Polydisperse Polymers in Water
Sammanfattning : The different steps in the dissolution process of polydisperse polymers in water have been studied. To that end, poly(ethylene oxide), dextran and hydroxypropyl methylcellulose tablets varying widely in polydispersity have been produced by mixing low molecular weight and high molecular weight samples in different proportions.
