A Hybrid Biomass Hydrothermal Gasification- Solid Oxide Fuel Cell System Combined with Improved CHP Plant for Sustainable Power Generation
(Journal article; Peer reviewed, 2017)The most popular technique, so far, for biomass waste to energy conversion has been incineration, but this technique has raised a lot of objection among nature activists due to the release of particulate matter and pollutants ... -
A kinetic study on simultaneously boosting the mass and fixed-carbon yield of charcoal production via atmospheric carbonization
(Journal article; Peer reviewed, 2017)The mass and fixed-carbon yield of charcoal produced from woody biomass via atmospheric carbonization can be simultaneously improved by harnessing the phenomenon of secondary char formation as a result of prolonged contact ... -
A New Foundation Model for Integrated Analyses of Monopile-based Offshore Wind Turbines
(Journal article; Peer reviewed, 2017)Offshore wind turbines are highly dynamic and tightly coupled systems subjected to variable cyclic loads. Designing and optimizing the support structure is a complex task, where several load scenarios have to be analysed ... -
A probabilistic-based approach for predicting mould growth in timber building envelopes: Comparison of three mould models
(Journal article; Peer reviewed, 2017)This paper applies a probabilistic-based approach as a methodology to analyze and compare the mould growth computations’ results from three different mould models. This approach, instead of the conventional deterministic ... -
A review and comparison of floating offshore wind turbine model experiments
(Journal article; Peer reviewed, 2016)Floating off shore wind turbines provide more access to deeper water than conventional fixed bottom wind turbines, which expands the viable area for wind energy development, reduces visibility from shore, and can potentially ... -
A review of slamming load application to offshore wind turbines from an integrated perspective
(Journal article; Peer reviewed, 2017)In harsh sea conditions, it is possible for offshore wind turbines (OWTs) to be exposed to slamming loads due to breaking waves, especially plunging breaking waves. These slamming loads lead to significant structural ... -
A state-of-art review of retrofit interventions in buildings towards nearly zero energy level
(Journal article; Peer reviewed, 2017)Unmistakably, buildings retrofitting brings the possibilities to reduce energy use and greenhouse gas emissions. However, selecting specific retrofit strategies is complex and requires careful planning. There are already ... -
Accurate measurements of CO2 rich mixture phase equilibria relevant for CCS transport and conditioning
