Numerical Analysis of an Articulated Hybrid Offshore Wind Turbine Concept
(Peer reviewed; Journal article, 2023)The concept of a "hybrid offshore wind turbine" originated from articulated loading platforms (ALPS). In this study, we have developed a concept design for the major structural components. Orcaflex was used to create a ... -
Numerical analysis of erosion due to nanoparticles in a pipe elbow
(Journal article; Peer reviewed, 2018)Flows of fluids laden with small particles in pipes are common in industry. An interesting and still unexplored issue is erosion of walls due to impact of particles. The main focus of our research was on nanoparticles. ... -
Numerical analysis of fire-driven smoke plumes in the atmosphere
(Master thesis, 2017)Plumes originating from fires may serve as a risk for people and environmental safety. Depending on what fuels a fire the content of the plume will vary [1]. From simple carbonaceous soot particulates, known to cause ... -
