Hydroplastic response of a square plate due to impact on calm water
(Peer reviewed; Journal article, 2020)This paper investigates large, plastic deflections of a square plate due to impact on calm water. Most research in the area has examined linear elastic structural responses to such impact, but hydrodynamic responses during ... -
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 ... -
Hydropower operations in groundwater-influenced rivers: implications for Atlantic salmon, Salmo salar, early life stage development and survival
(Journal article; Peer reviewed, 2016)During their early life stages (egg maturation, hatching, alevin development), between late autumn and early spring, young Atlantic salmon are exposed to surface-groundwater interactions in the hyporheic zone and may depend ... -
Hydropower Production in Future Climate Scenarios: The Case for Kwanza River, Angola
(Journal article; Peer reviewed, 2016)Climate change is altering hydrological processes with varying degrees in various regions of the world and remains a threat to water resources projects in southern Africa. The likely negative impacts of changes in Africa ... -
Hydropower Production in Future Climate Scenarios; the Case for the Zambezi River
(Journal article; Peer reviewed, 2016)Climate change remains a threat to water resources projects in southern Africa where impacts resulting from changes in climate are projected to be negative and worse than in most other regions of the world. This work ... -
Hydropower Providing Flexibility for a Renewable Energy System: Three European Energy Scenarios

Hydropower Providing Flexibility for a Renewable Energy System: Three European Energy Scenarios
(Report, 2018)The Horizon 2020 Project ‘Increasing the value of Hydropower through increased Flexibility (HydroFlex)’ aims towards scientific and technological breakthroughs to enable hydropower to operate with very high flexibility in ... -
Hydropower‐driven thermal changes, biological responses and mitigating measures in northern river systems
(Peer reviewed; Journal article, 2021)Water temperatures control life histories and diversity of aquatic species. Hydropower regulation, particularly in high head systems, alters natural water temperature regimes, which may have profound and long-term impacts ... -
Hydrostatic Stability and Hydrodynamics of a Floating Wind Turbine Platform Integrated with Oscillating Water Columns: A Design Study
(Peer reviewed; Journal article, 2024)One of the challenges in the installation of Floating Wind Turbines (FWTs) is the occurrence of undesired resonant motions under environmental conditions, which adversely impact their lifespan, maintenance cost, components ... -
Hydrothermal Gasification of Biogas Digestate: a Parametric Study Using a Matlab-based Code
(Peer reviewed; Journal article, 2023)In this work, effect of process parameters on hydrothermal gasification (HTG) of biogas digestate are thermodynamically investigated using a Matlab-based code, which is capable of modelling the effects of the feedstock’s ... -
Hydrothermal Gasification of Biogas Digestate: a Thermodynamic Study on Effects of Process Parameters Using Aspen Plus

Hygienic standards and practices in Norwegian salmon Processing plants
(Journal article; Peer reviewed, 2017)The farmed salmon industry is important economically for several countries with Norway as the main producer constituting 53% of the world total. Bacterial contamination of salmon products may occur during processing, ... -
HyGreGel: A new class of gel systems for water diversion by in-depth reservoir placement
(Doctoral theses at NTNU;2019:336, Doctoral thesis, 2019)High water production is typically a major problem late in the life cycle of a water flooded hydrocarbon reservoir. Reservoir heterogeneity plays a significant role in creating this problem. An example is highly permeable ... -
Hygroscopic buffering effects in exposed cross-laminated timber surfaces and indoor climate in a Norwegian primary school
(Peer reviewed; Journal article, 2022)Laboratory studies have shown that wood has hygroscopic properties. When used as a construction material in buildings, it can thus influence indoor relative humidity and temperature. Ventilation can affect indoor climate ... -
Hygrothermal Aging of Amine Epoxy: Reversible Static and Fatigue Properties
(Journal article; Peer reviewed, 2018)Fiber-reinforced polymers (FRP) are widely used in structural applications. Long-term properties of such materials exposed to water are of high concern and interest, especially for subsea and offshore applications. The ... -
Hygrothermal Modeling of Masonry with Interior Insulation Retrofit - Perspectives on hygrothermal performance and modeling-uncertainty
(Doctoral theses at NTNU;2024:43, Doctoral thesis, 2024)Energy retrofit of existing buildings is mainly an endeavor to reduce energy consumption. Interior insulation retrofit of masonry falls among retrofit measures in this regard. However, interior insulation of masonry may ... -
Hygrothermal performance of ventilated wooden cladding
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:31, Doctoral thesis, 2010)This PhD project contributes to more accurate design guidelines for high-performance building envelopes by analysis of hygrothermal performance of ventilated wooden cladding. Hygrothermal performance is defined by cladding ... -
Hygrothermal Properties of Compressed Earthen Bricks
(Journal article; Peer reviewed, 2018)The present study investigates the relationship between bulk density and hygrothermal behaviour of compressed earthen bricks. The experimental results show that the thermal conductivity linearly increases from 0.5228 W/(m ... -
Hygrothermal Simulation of Interior Insulated Brick Wall - Perspectives on Uncertainty and Sensitivity
(Peer reviewed; Journal article, 2023)Energy retrofit of existing masonry buildings has become attractive to meet demands for reduction in energy consumption. Retrofit may, however, introduce moisture risk that needs to be assessed. Hygrothermal simulation ... -
