A simple embedded discrete fracture-matrix model for a coupled flow and transport problem in prous media
Odsæter, Lars Hov; Kvamsdal, Trond; Larson, Mats (Journal article; Peer reviewed, 2018)Accurate simulation of fluid flow and transport in fractured porous media is a key challenge in subsurface reservoir engineering. Due to the high ratio between its length and width, fractures can be modeled as lower ... -
Design of a novel hybrid process for membrane assisted clean hydrogen production with CO2 capture through liquefaction
Kim, Donghoi; Liu, Zhongxuan; Anantharaman, Rahul; Riboldi, Luca; Odsæter, Lars Hov; Berstad, David Olsson; Peters, Thijs; Polfus, Jonathan; Malerød-Fjeld, Harald; Gundersen, Truls (Peer reviewed; Journal article, 2022)This work introduces a novel hybrid concept to produce H2 from natural gas by using the protonic membrane reformer (PMR) with liquefaction based CO2 capture system. For process intensification, recycling of the off-gas ... -
Experimental Investigation into the Consequences of Release of Liquified Hydrogen onto and under Water
van Wingerden, Kees; Kluge, Martin; Habib, Abdel Karim; Skarsvåg, Hans Langva; Ustolin, Federico; Paltrinieri, Nicola; Odsæter, Lars Hov (Peer reviewed; Journal article, 2022)Large-scale experiments have been performed to investigate the possible consequences of realistic amounts of liquified hydrogen (LH2) encountering water. The experiments aimed at simulating an accidental release of LH2 ... -
Liquid Hydrogen Spills on Water—Risk and Consequences of Rapid Phase Transition
Odsæter, Lars Hov; Skarsvåg, Hans Langva; Aursand, Eskil; Ustolin, Federico; Reigstad, Gunhild Allard; Paltrinieri, Nicola (Peer reviewed; Journal article, 2021)Liquid hydrogen (LH2 ) spills share many of the characteristics of liquefied natural gas (LNG) spills. LNG spills on water sometimes result in localized vapor explosions known as rapid phase transitions (RPTs), and are a ... -
Postprocessing of non-conservative flux for compatibility with transport in heterogeneous media
Wheeler, Mary F.; Kvamsdal, Trond; Odsæter, Lars Hov; Larson, Mats (Journal article; Peer reviewed, 2016)A conservative flux postprocessing algorithm is presented for both steady-state and dynamic flow models. The postprocessed flux is shown to have the same convergence order as the original flux. An arbitrary flux approximation ... -
Reservoir Simulation in Heterogeneous and Fractured Reservoirs
Odsæter, Lars Hov (Doctoral theses at NTNU;2018:165, Doctoral thesis, 2018)Summary of the thesis This thesis addresses simulation of flow and transport of fluids and fluid components in heterogeneous and fractured porous media. Reservoir simulation is a key component in several engineering ... -
Risk and Consequences of Rapid Phase Transition for Liquid Hydrogen
Aursand, Eskil; Odsæter, Lars Hov; Skarsvåg, Hans Langva; Reigstad, Gunhild Allard; Ustolin, Federico; Paltrinieri, Nicola (Chapter, 2020)Safe handling of liquid hydrogen (LH2) has gained extra attention over the last years due to an increase in usage to mitigate climate changes. Rapid phase transition (RPT) is a potential safety concern when cryogens, like ... -
Theories and Mechanism of Rapid Phase Transition
Ustolin, Federico; Odsæter, Lars Hov; Reigstad, Gunhild Allard; Skarsvåg, Hans Langva; Paltrinieri, Nicola (Peer reviewed; Journal article, 2020)Light hydrocarbons and hydrogen can replace high-alkane fuels with the benefit of reduced CO2 emissions. Their liquefaction to a cryogenic state is one of the most suitable solutions for storage and transport. An unexpected ...
