Hydraulic Design of Francis Turbine Exposed to Sediment Erosion
(Master thesis, 2011)Sediment erosion is a large problem for turbines operated in sand laden water, especially in the Himalayas and the Andes Mountains, where the contents of hard minerals in the rivers are high. A program called RenewableNepal ... -
Hydraulic design of Francis turbine exposed to sediment erosion
(Master thesis, 2012)High concentrations of sediments is a serious problem for hydropower stations in the Himalayas and the Andes Mountains. For run-of-river power plants sediment causes heavy erosion even with settling basins. This leads to ... -
Hydraulic resistance, shock wave attenuation and gaseous detonation extinction in granular materials
(Doktoravhandlinger ved NTNU, 1503-8181; 65, Doctoral thesis, 2002)Military and civil installations can be equipped with a granular filter, for example in air inlet systems to protect against blast waves. Granular filters also have a certain potential to replace shock valves and to work ... -
Hydraulic scale modelling and thermodynamics of mass oscillations in closed surge tanks
(Journal article; Peer reviewed, 2015)The design and results from a hydraulic scale model of mass oscillations in a hydropower plant with a closed surge tank constructed as an underground rock cavern are presented. The results from the model test of an existing ... -
Hydrodynamic and magnetohydrodynamic turbulence : some numerical experiments
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:128, Doctoral thesis, 2004)This thesis consists of a brief introduction to hydrodynamics and magnetohydrodynamics, followed by five articles that address different aspects of hydrodynamic and magnetohydrodynamic turbulence. Paper A: Bottleneck ... -
Hydrodynamic Damping of a Fluttering Hydrofoil in High-speed Flows
(Journal article; Peer reviewed, 2018)A hydrofoil resembling a high head Francis runner blade was submerged in a rectangular channel and attached to the walls in a fixed-beam configuration. The hydrofoil was excited by piezoelectric Macrofiber composite actuators ... -
Hydrodynamics of non-circular bluff bodies
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:302, Doctoral thesis, 2011)The present doctoral thesis is devoted to investigate and study the complex three-dimensional wake flow dynamics from different types of non-circular bluff bodies. The bluff body configuration considered in this work is ... -
Hydrogen and Wet Gas Compressor Analysis
(Master thesis, 2020)Verdens energiproduserende industri står overfor flere utfordringer i sin søken etter å minimere ut- slippene av drivhusgasser. Nyvinninger i lav- og nullutslipps energiproduksjon og forventninger om videre innovasjon ... -
Hydrogen for å skape nettfleksibilitet til landstrømanlegg ved Trondheim Havn
(Bachelor thesis, 2023)Cruiseindustrien hadde i 2021 et utslipp på omtrent 300 000tonn CO2-ekvivalenter. Det meste kommer fra skipenes fremdrift, men de fleste skip må idag benytte seg av dieselgeneratorer i anløp. Det er estimert et utslipp på ... -
Hydrogen production by water splitting using gas switching technology
(Peer reviewed; Journal article, 2020)This study demonstrates a novel“Gas Switching Water Splitting (GSWS)”technology for production of pure H2with integrated CO2capture. The reactor concept is based on the chemical looping technology where an oxygencarrier ... -
Hydrogen production from methanol partial oxidation through the catalyst prepared using torrefaction liquid products
(Peer reviewed; Journal article, 2020)This study developed a novel application of torrefaction liquid products (TLPs) for acidic catalyst sol-gel synthesis of SiO2 from tetraethyl orthosilicate (TEOS) to improve the thermal stability of Al2O3 catalyst supporter. ... -
Hydrogen Storage: Thermophysical data and flow properties for some porous media
(Master thesis, 2010)Two rigs have been developed and built to measure thermal conductivity and permeability for porous materials. The intention of the rigs is to investigate the properties of some hydrogen adsorption materials. The materials ... -
Hydrogen-Powered Service Vessel for the Norwegian Fish Farming Industry
(Bachelor thesis, 2019)Denne bacheloroppgaven har tatt sikte på å sammenligne et hydrogen-brenselscellesystem, et batterisystem, og en kombinasjon av de to til å drifte en servicekatamaran, med navn Fosna Orion. Fosna Orion brukes i den norske ... -
Hydropower
(Chapter, 2021)Hydropower has a very long tradition in many countries and was first used to provide working power for grinding corn, sawing timber and other previously manual tasks. The development of the modern turbine took a big step ... -
