Coupled CO2-well-reservoir simulation using a partitioned approach: effect of reservoir properties on well dynamics
(Peer reviewed; Journal article, 2020)We present a model framework for dynamic simulation of the flow of (Formula presented.) and other components in an injection well coupled with a near-well reservoir. With a partitioned approach, we employ numerical methods ... -
A combined fluid-dynamic and thermodynamic model to predict the onset of rapid phase transitions in LNG spills
(Peer reviewed; Journal article, 2020)Transport of liquefied natural gas (LNG) by ship occurs globally on a massive scale. The large temperature difference between LNG and water means LNG will boil violently if spilled onto water. This may cause a physical ... -
Upward and downward two-phase flow of in a pipe: Comparison between experimental data and model predictions
(Peer reviewed; Journal article, 2021)In order to deploy capture and storage (CCS) systems to mitigate climate change, it is crucial to develop reliable models for design and operational considerations. A key element of the system is the interface between ... -
Electromagnetic Oscillation Origin Location in Multiple-Inverter-Based Power Systems Using Components Impedance Frequency Responses
(Peer reviewed; Journal article, 2021)Existing impedance-based stability criterion (IBSC) for electromagnetic stability assessment of multiple-grid-connected-inverter (GCI)-based power systems suffers from several limitations. First, global stability feature ... -
Cerman: Software for simulating streamer propagation in dielectric liquids based on the Townsend–Meek criterion
(Peer reviewed; Journal article, 2021)We present a software to simulate the propagation of positive streamers in dielectric liquids. Such liquids are commonly used for electric insulation of high-power equipment. We simulate electrical breakdown in a needle–plane ... -

Virtual Friction for Oscillation Damping and Inertia Sharing from Multi-Terminal VSC-HVDC Grids
(Chapter; Peer reviewed, 2020)This paper proposes a control scheme for multi-terminal HVDC (MTDC) interconnections that introduces an effect equivalent to a mechanical coupling between asynchronous ac networks providing damping of frequency oscillations ... -
Thermal Characteristics in Supercritical CO2 Along Heating Tube
(Sciences et technique du froid;2020:14, Chapter; Peer reviewed, 2020)The system using CO2 as a refrigerant such as heat pump or Rankine cycle, depends greatly on the phase state and physical properties of CO2. In the present study, as a basic research on CO2 in the supercritical state, an ... -
Integration of heat pumps with natural working fluids into a neighborhood energy system
(Sciences et technique du froid;2020:14, Chapter; Peer reviewed, 2020)Combining heat pumps (HP) with other renewables, e.g. solar thermal collectors, photovoltaics and energy storage systems can contribute to the growth of future zero emission societies. This article investigates HP integration ... -
