Despite current policy-driven emphases ... -
A Final Move to Your Own House
(SINTEF Proceedings;8, Chapter; Peer reviewed; Conference object, 2021)Objective – What makes a house a home? Many residents of care centres do not feel at home. 'This is not my own house', is what we heard in many of our conversations with residents. What makes the current houses into homes? ... -
A Lagrangian‐Eulerian hybrid model for the simulation of direct reduction of iron ore in fluidized beds
(SINTEF Proceedings;2, Chapter, 2017)Fluidized bed and moving bed reactors are one of the most important technologies in several branches of process industry. Especially, it is known since decades that iron can be reduced rapidly and efficiently from iron ... -
A method for determining the time-dependent indoor CO2 concentration to evaluate air hygiene
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)This paper deals with new ways to describe and assess indoor air CO2-levels to provide a sufficient clarity. Besides common illustrations of measured or calculated CO2 concentrations over a certain period of time different ... -
A multi-scale model for oxygen carrier selection and reactor design applied to packed bed chemical looping combustion
(SINTEF Proceedings;1, Chapter, 2015)Proper selection of a catalyst shape (or a particle shape) can improve the performance of a gas-solid packed bed reactor. The particle shape affects the packing structure and the transport phenomena within the packed bed. ... -
A multifluid‐PBE model for a slurry bubble column with bubble size dependent velocity, weight fractions and temperature
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)With kinetic gas theory as a starting point, equations of change for total mass, species mass, momentum and inner energy are developed for the dispersed gaseous phase and implemented to describe the Fischer-Tropsch synthesis ... -
