1. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.

2. Numerical and experimental dynamic analyses of the Vega Pedestrian bridge including seasonal effects
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : As timber structures become increasingly relevant and sought after – since they enable improvements in building time while reducing a structure’s life cycle impacts – streamlining their design can have meaningful economic and environmental implications.For timber footbridges, its design is frequently governed by serviceability criteria linked to excessive vibrations.

4. Experimental Investigation of Added Mass and Damping on a Model Kaplan Turbine for Rotor Dynamic Analysis
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : The concept of added hydrodynamic properties such as added mass is of importance in modern hydropower development, mainly for rotor dynamic calculations. Added mass could result in reduced natural frequencies and altered mode compared to existing simulation models. LÄS MER
5. Application of the open sourcecode Nemoh for modelling ofadded mass and damping in shipmotion simulations
Master-uppsats, KTH/Marina systemSammanfattning : Two different numerical tools were considered, the first one is a seakeeping method developed by KTH Ship Dynamics Research Program. It utilizes strip theory and Lewis forms and is further addressed as SMS. LÄS MER
