The objective of this study is to determine the potential energy savings and thermal comfort benefits of exposing concrete in the ceiling to the indoor air as an alternative to suspended ceiling. The performances were assessed through monitoring of room air and surface temperatures in an office...
Recently special attention is paid to make fuel and energy using anaerobic co-digestion of animal wastes, crop and crop residues, municipal solid waste (MSW), as well as municipal sewage sludge. One of the options for improving the biogas yields of anaerobic digestion of solid wastes is co-digestion...
This article deals with the techno‐economic analysis of biomass to liquid fuel (BTL) production under Norwegian conditions. The study goal is to produce transportation fuel via Fischer‐Tropsch synthesis with combined heat production and electricity as a co‐product. The biorefinery is fed by...
The biorefineries are fed by 150 MWth (HHV basis) of biomass of woodchips and torrefied woodchips. The biorefinery design is based on high temperature entrained flow gasification followed by catalytic Fischer- Tropsch synthesis. Process modelling software (Aspen Plus) is utilized to organize the...
A model for two-phase pipeline flow of CO2 with phase transfer is presented. Two different relaxation models for phase transfer are developed. The system of equations is solved by splitting it into a hyperbolic conservation law and a relaxation ODE, solved by a multi-stage (MUSTA) finite volume scheme...
FE computations are performed to investigate the current load on anodes and pipeline in the current transfer zone (CTZ) of a Direct Electrical Heated flowline. It is shown that there may be great differences in the current load on the anodes, and that there is a significant increase in the current...
This paper presents a small signal eigenvalue analysis applied to a droop-controlled HVDC terminal based on the Modular Multilevel Converter (MMC) topology. The applied linearised model is derived from previous modelling efforts recently proposed in the literature, which rely on the application of...
