Two-fluid CFD model for R744 two-phase ejectors
(Chapter, 2020)This paper presents early results from a novel two-fluid Eulerian-Eulerian multiphase model for R744 two-phase ejectors, which to the authors knowledge has not previously been presented in literature. As opposed to previous ... -
Two-parameter fracture model for cortical bone
(Peer reviewed; Journal article, 2016)The analysis of the bone fracture behaviour is fundamental for prevention, diagnosis and treatment of traumas. In the present paper, an experimental analysis of the fracture behaviour of a bovine femoral cortical bone ... -
Two-phase Flow Distribution in Heat Exchanger Manifolds
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:1, Doctoral thesis, 2004)The current study has investigated two-phase refrigerant flow distribution in heat exchange manifolds. Experimental data have been acquired in a heat exchanger test rig specially made for measurement of mass flow rate and ... -
TWO-PHASE FLOW INSTABILITIES AND FLOW MAL-DISTRIBUTION IN PARALLEL CHANNELS
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:245, Doctoral thesis, 2013)Boiling flow instabilities are present in several heat exchanging systems, covering different applications and scales. Two–phase flow unstable phenomena can take place in nuclear reactors, cryogenic and chemical processes ... -
Two-phase Flow Instabilities during Flow Boiling and Control of Wettability by Micro-structured Surfaces
(Doctoral theses at NTNU;2018:245, Doctoral thesis, 2018)Boiling heat transfer is of relevance in a variety of applications in power and process industries. In spite of the vast research performed in the last decades, fundamental questions about mechanisms related to the boiling ... -
Two-Phase Flow Measurement
(Master thesis, 2010)The use of multiphase flow meters (MPFMs) increase each year. The main reasons for this are the cost benefits connected to the use of such a meter by eliminating exclusive lines to the test separator and the test separator ... -
Two-Phase pipeflow simulations with OpenFoam
(Master thesis, 2013)The main purpose of this thesis is to develop two-phase simulations using OpenFOAM. Two different situations are studied: open and closed channel flow. Different parameters are changed in each case to obtain different ... -
Two-Phase Slug Flow Experiments with Viscous Liquids
(Doctoral thesis at NTNU;2016:109, Doctoral thesis, 2016)The challenges behind the multiphase transport of oil and gas mixtures are increasing as the oil and gas industry is moving towards production from non-conventional reservoirs and in remote locations. Transport of high ... -
Two-Phase Two-Layer Depth-Integrated SPH-FD Model: Application to Lahars and Debris Flows
(Peer reviewed; Journal article, 2022)The complex nature of debris flows suggests that the pore-water pressure evolution and dewatering of a flowing mass caused by the high permeability of soil or terrain could play an essential role in the dynamics behavior ... -
A Two-Stage Approach for Individual Tree Segmentation From TLS Point Clouds
(Peer reviewed; Journal article, 2022)Individual tree segmentation in forest scenes provides a foundation for forest ecosystem modeling and biodiversity assessment applications. Existing approaches work well for cases where trees do not grow in layers. However, ... -
Two-stage evaporator for R744 heat pumps using greywater as heat source
(Peer reviewed; Journal article, 2023)Heat pumps are pinpointed as a key technology in decarbonizing buildings' heat supply, which is currently dominated by fossil-fuel based systems. To minimize the environmental impact of heat pumps over their lifetime, ... -
Two-terminal reliability analysis for multi-phase communication networks
(Journal article, 2016)Abstract: Most researches of network reliability generally assume that the system structures do not change with time. This paper presents the concept of multi-phase network systems (MPNS) to consider dynamic characteristics ... -
Two-way coupled fluid-structure interaction of gas-liquid slug flow in a flexible riser: Small-scale experiments and simulations
(Journal article; Peer reviewed, 2019)Flexible risers might be subjected to large pressure and density fluctuations when transporting multiphase mixtures as different flow patterns may take place. Those fluctuations might induce large forces on the structure, ... -
