An Extended Corresponding States Equation of State (EoS) for CCS Industry
(Journal article; Peer reviewed, 2015)For a good design of all the processes in Carbon Capture and Storage, the thermodynamics of the CO2 and CO2 mixtures should be accurately predicted. Among these mixtures are CO2-water systems that are very difficult to ... -
CFD-DEM simulation of biomass gasification with steam in a fluidized BEd reactor
(Journal article; Peer reviewed, 2015)A comprehensive CFD–DEM numerical model has been developed to simulate the biomass gasification process in a fluidized bed reactor. The methodology is based on an Eulerian–Lagrangian concept, which uses an Eulerian method ... -
Influence of drag force correlations on periodic fluidization behavior in Eulerian-Lagrangian simulation of a bubbling fluidized bed
(Journal article; Peer reviewed, 2013)In this paper, an Eulerian–Lagrangian approach, in which the gas flow is solved by the volume-averaged Navier–Stokes equation and the motion of individual particles is obtained by directly solving Newton's second law of ... -
Minimum entropy production in a distillation column for air separation described by a continuous non-equilibrium model
(Journal article; Peer reviewed, 2020)In this work, we apply the rate-based model of Taylor and Krishna to describe the separation of air in a low-pressure, packed distillation column. By use of numerical optimization, we identify the temperature profile for ... -
Modelling CO2 - water mixture thermodynamics using various equations of state (EoSs) with emphasis on the potential of the SPUNG EoS
(Journal article; Peer reviewed, 2014)CO2–water is a very important mixture in the Carbon Capture and Storage (CCS) industry. The mixture can have a broad range of concentrations, from water as an impurity in CO2 transport to high water concentrations in ... -
On the choice of closure complexity in anisotropic drag closures for filtered Two Fluid Models
(Peer reviewed; Journal article, 2019)Filtered Two Fluid Models (fTFMs) aim to enable accurate industrial-scale simulations of fluidized beds by means of closures accounting for the effects of bubbles and clusters. The present study aims to improve anisotropic ...
