Non-Destructive Surface Characterization of Wood Façade Materials and Wood Fungi by Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy
(Doctoral theses at NTNU;2016:299, Doctoral thesis, 2016)Wood material is the dead xylem part of a tree that is being used for building construction, furniture, decorative items etc. Building façade is the outer envelope of a building. Wood façade materials are exposed against ... -
Numerical Modelling and Experiments on Sea Spray Icing
(Doctoral thesis at NTNU;2014:338, Doctoral thesis, 2014)Oil and gas activities in the cold seas are endangered by icing. Icing may occur when water spray or moisture is deposited on a vessel or offshore structure above sea level and the air temperatures is below the freezing ... -
Numerical modelling of air entrainment: In hydraulic engineering
(Doctoral theses at NTNU;2021:62, Doctoral thesis, 2021)Air entrainment in water flows is a natural phenomenon prone to take place when energy is dissipated in flowing water. In nature, air entrainment appears as white water in waterfalls or in waves breaking on the beach. ... -
Numerical Modelling of Arctic Costal Erosion
(Doctoral theses at NTNU;2023:213, Doctoral thesis, 2023)Arctic coastal erosion is a growing concern as global climate change affects the planet. Unlike low-latitude and mid-latitude coastal areas, the sediments along Arctic coastlines are often frozen, even during summer. It ... -
