1. Assessment of Experimental, Computational, and Combined EFD/CFD Methods for Ship Performance Prediction
Sammanfattning : In today’s highly competitive market, alongside increasingly stringent regulatory requirements, the precise prediction of ship performance has assumed paramount importance for both design verification and operational evaluations. This thesis addresses the need for a comprehensive assessment of Experimental Fluid Dynamics (EFD), Computational Fluid Dynamics (CFD), and their combination to enhance the accuracy of performance predictions.

2. Fluid Dynamics and Granular Growth in High Shear Wet Granulation
Sammanfattning : High shear wet granulation is a key step in the manufacturing of tablets in the pharmaceutical industry. From the pharmaceutical industry’s point of view, there is a desire for predictive quantitative process models to be able to make in-silico process and scale-up simulations, which would shorten and reduce the cost of technology transfer from laboratory scale to manufacturing scale in drug development.

3. Propeller-Hull Interaction Effects in Calm Water and Regular Head Waves
Sammanfattning : In order to design fuel-efficient ships and install compatible propulsion systems, ship and propeller designers need to know the potential effects of the interactions between different ship components, e.g., hull, propeller, appendages and machinery, on the ship performance at sea.

4. Improved Power Predictions of Ships Using Combined CFD/EFD Methods for the Form Factor
Sammanfattning : Performance prediction of a ship is one of the most important tasks during the design phase. Once the design is finalized, the speed attained at a certain power consumption has to be verified with the most accurate prediction as it is specified at the contract of a new ship order and also required by the legal authorities.

5. On the establishment of effective condition-based maintenance for oil-filled electrical transformers to reduce failures due to copper corrosion problems and its role toward sustainable energy
Sammanfattning : Oil-filled electrical transformers are critical equipment for modern societies where a sustainable energy supply is required. Recently, many severe fire and explosion accidents of transformers have been reported due to copper corrosion problems in the form of copper sulfide deposits on the windings. LÄS MER
