Three layers of energy law for examining CO2 transport for carbon-capture and storage
(Journal article; Peer reviewed, 2017)This research is a legal analysis concerning four scenarios for cross-border carbon dioxide (CO2) transport that could increase the deployment of carbon-capture and storage (CCS) deployment in Europe. The legal analysis ... -
Three-dimensional Linear Eddy Modeling of a Turbulent Lifted Hydrogen Jet Flame in a Vitiated Co-flow
(Journal article; Peer reviewed, 2018)A new methodology for modeling and simulation of reactive flows is reported in which a 3D formulation of the Linear Eddy Model (LEM3D) is used as a post-processing tool for an initial RANS simulation. In this hybrid approach, ... -
Three-dimensional unsteady numerical simulation of a 150 kWth full-loop chemical looping combustion pilot with biomass as fuel: A hydrodynamic investigation
(Peer reviewed; Journal article, 2022)A hydrodynamic model for a full Chemical Looping Combustion (CLC) unit was established, and simulations performed using the code NEPTUNE_CFD, which is based on an Euler-Euler approach. The unit is a 150 kWth pilot constructed ... -
