The scientific and community-building roles of the Geoengineering Model Intercomparison Project (GeoMIP) – past, present, and future
(Peer reviewed; Journal article, 2023)The Geoengineering Model Intercomparison Project (GeoMIP) is a coordinating framework, started in 2010, that includes a series of standardized climate model experiments aimed at understanding the physical processes and ... -
Screening of Future-Proof Working Fluids for Industrial High-Temperature Heat Pumps up to 250 °C (Part I)
(Chapter, 2021)If industry wants to phase out fossil steam boilers, heat pumps will have to produce steam at a temperature of about 160 °C or higher, as this is a kind of standard in current steam systems. Even 250 °C is used in some ... -
Screening of Future-Proof Working Fluids for Industrial High-Temperature Heat Pumps up to 250 °C (Part II)
(Chapter, 2021)With the new European Green Deal, the EU commission has committed to making Europe the world’s first climate-neutral continent. This also involves reduction of fossil fuel consumption in furnaces and boilers for the ... -
Scrutinizing proposed extensions to the Eddy Dissipation Concept (EDC) at low turbulence Reynolds numbers and low Damköhler numbers
(Peer reviewed; Journal article, 2022)Recent proposals to modify or extend the Eddy Dissipation Concept are investigated and compared to the standard EDC. The results with respect to the underlying principles of EDC are examined. A total of four different ... -
Secondary Flow and Sediment Erosion in Francis Turbines
(Doctoral theses at NTNU;2018:190, Doctoral thesis, 2018)Sediment erosion of the hydropower turbine components is one of the key challenges due to the constituent of hard particles in the rivers of Himalayas and Andes. In these regions, Quartz is found as a main constituent (more ... -
Secondary flow fields in Francis turbines : mapping and analyzing dynamics in rotor-stator interaction and draft tube flow with novel methods
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:261, Doctoral thesis, 2012)Hydropower, and especially Francis turbines, for electricity production has a history of more than 100 years and has proved to be one of the most efficient ways of utilizing renewable energy for electricity production. ... -
Secrecy Performance of Correlated α-μ Fading Channels
(Journal article; Peer reviewed, 2019)This paper investigates the secrecy performance of the classical Wyner’s wiretap model, where the main channel and eavesdropper channel experience correlated α-μ fading. Novel and exact expressions for the average secrecy ... -
Sectoral Model of the Cement Industry Using Input-Output Analysis

Sediment Erosion in Francis Turbines
(Master thesis, 2009)The high concentration of sediments in the rivers near the Andes and the Himmalayas, is a large problems for run-of-river power plants. Small particles of quartz, which is a hard and sharp mineral, damage the turbine and ... -
Sediment erosion in Francis turbines
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:250, Doctoral thesis, 2013)Sediment erosion is a major challenge for run-of-river power plants, especially during flood periods. Due to the high content of hard minerals such as quartz and feldspar carried in the river, substantial damage is observed ... -
Sediment Erosion in Hydro turbines
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:104, Doctoral thesis, 2010)Sediment erosion is caused by the dynamic action of sediment flowing along with water impacting against a solid surface. Hydraulic turbine components operating in sediment-laden water are subject to abrasive and erosive ... -
