Hybridization of complete PLCA and MRIO databases for a comprehensive product system coverage
(Peer reviewed; Journal article, 2020)Process‐based Life Cycle Assessments (PLCA) rely on detailed descriptions of extensive value chains and their associated exchanges with the environment, but major data gaps limit the completeness of these system descriptions ... -
Hybridization of General Cargo Ships to meet the Required Energy Efficiency Design Index
(Master thesis, 2015)In this thesis a hybrid propulsion system is proposed for a general cargo ship with the aim to meet the required Energy Efficiency Design Index (EEDI). The study has investigated how a hybrid propulsion system will influence ... -
Hydrate Prevention by Anti-Agglomerants - Parameters Impacting Flow Performance in Systems Where Hydrates are Present
(Master thesis, 2017)Natural gas hydrates are crystalline compounds that, under the right pressure and temperature conditions, may form in hydrocarbon pipelines, causing transport complications. Several methods of countering this have been ... -
Hydration of Portland cement accelerated by C-S-H seeds at different temperatures
(Peer reviewed; Journal article, 2020)C-S-H seeds have potential application as accelerators in oil well cementing pastes. Typical oil well conditions present elevated temperatures; nevertheless, is not clear how such temperatures affect the nucleation process ... -
Hydration Status During Commercial Saturation Diving Measured by Bioimpedance and Urine Specific Gravity
(Peer reviewed; Journal article, 2022)Excessive fluid loss triggered by hyperbaric pressure, water immersion and hot water suits causes saturation divers to be at risk of dehydration. Dehydration is associated with reductions in mental and physical performance, ... -
Hydraulic and structural evaluation of rockfill dam behavior when exposed to throughflow and overtopping scenarios
(Doctoral theses at NTNU;2020:227, Doctoral thesis, 2020)Dams are vulnerable to extreme flood events in turn leading to accidental overtopping. This inparticular applies to rockfill dams comprised of pervious and erodible material. Obtaining better understanding of behavior of ... -

Hydraulic capacity of culverts under sediment transport
(Master thesis, 2014)Sedimentation frequently causes an extensive blockage in culvert which may reduce its design capacity. Culvert guidelines which are extensively used reveal little details about sedimentation in culvert. Requirement of the ... -
Hydraulic capacity of culverts under sediment transport - Multibarrel Setup
(Master thesis, 2014)As a part of the research program Natural hazards Infrastructure for Floods and Landslides (NIFS), the hydraulic performance of the culverts are presently investigated in a scale model study carried out in the NTNU ... -
Hydraulic Characterization of Ceramic Foam Filters Used in Aluminum Filtration
(Peer reviewed; Journal article, 2023)Ceramic Foam Filters (CFF) are frequently used during the filtration of aluminum (Al) melts to produce high-quality products. In the present study, the physical and hydraulic characteristics of alumina (Al2O3)-based CFF ... -
Hydraulic design of a Francis turbine that will be influenced by sediment erosion
(Master thesis, 2014)High amount of sediments in the Himalayas are at present a large problem for power companies in Nepal, preventing them of utilizing the large amount of hydro power available in the area. In the Jhimruk power plant the ... -
Hydraulic design of a turbine for energy recovery purposes
(Master thesis, 2023)Denne masteroppgaven fokuserer på design og analyse av en komplett Francis turbin for Framo AS med formål om energiutvinning i offshore-applikasjoner. Turbindesignet skiller seg fra konvensjonelt design ved at den ikke har ... -
