A linear State-Space Model of an Offshore Wind Turbine, Implemented in the STAS Wind Power Plant Analysis Program
(SINTEF Energi. Rapport;TR A7474, Research report, 2015)A set of MATlab/Octave scripts have been developed, which output state matrices describing the linearized aerolastic dynamics of an offshore wind turbine. The aerodynamic model is based on momentum balance,and includes ... -
Predicting NOx emissions from wood stoves using detailed chemistry and computational fluid dynamics
(Journal article; Peer reviewed, 2015)The present paper addresses NOx emissions from wood stoves through a computational fluid dynamics (CFD) modeling approach. The most significant route for NOx formation in traditional biomass combustion applications is the ... -
Wide-Band Transformer Modeling Including Core Non-Linear Effects
(Journal article; Peer reviewed, 2015)Wide-band, black-box transformer models can be obtained via frequency sweep measurements on transformer terminals followed by rational model extraction via passive curve fitting. These models do however not include core ... -
Investigation of non-ideal behavior of plate-fin heat exchangers in LNG services
(Peer reviewed; Journal article, 2015)Using a heat exchanger with several parallel channels in boiling services, static instabilities like the Ledinegg instabilities can occur, resulting from a combination of unfortunate operating conditions and the heat ... -
