Feasibility of Vis/NIR spectroscopy and image analysis as basis of the development of smart-drying technologies
(Chapter, 2018)Drying is a complex, dynamic, unsteady and nonlinear process that, when not optimized on a system level, may be responsible for (1) significant quality degradation and (2) energy wastage. Consequently, new drying technologies ... -
The LEANWIND suite of logistics optimisation and full lifecycle simulation models for offshore wind farms
(Journal article; Peer reviewed, 2018)The offshore wind sector has achieved significant cost reductions in recent years. However, there is still work to be done to maintain and surpass these savings across current and future farms. There is increased competition ... -
Work and Heat Integration: An emerging research area
(Journal article; Peer reviewed, 2018)The extension from Heat Integration (HI) and design of Heat Exchanger Networks (HENs) to including heating and cooling effects from pressure changing equipment has been referred to as Work and Heat Integration and design ... -

Numerical investigation of heat transfer in a CO2 two-phase ejector
(Journal article; Peer reviewed, 2018)In this paper, the influence of heat transfer in the walls of an R744 two-phase ejector on ejector performance was investigated. A numerical investigation was performed using a computational fluid dynamic (CFD) model of ... -
Performance evaluation of CO2 ejector system with parallel compressor for supermarket application
(Chapter, 2018)Evolution in modifications for CO2 system configuration came across from the last two decades has proven to hold the potential in order to improve the overall performance of the CO2 cooling system for various applications. ... -
Voltages and AC Corrosion on Metallic Tubes in Umbilical Cables Caused by Magnetic Induction From Power Cable charging Currents
(Journal article; Peer reviewed, 2018)Offshore umbilical cables often include both power cables and elements such as metallic tubes and signal cables. It was concluded from a recent failure of stainless tubes that AC corrosion was the failure cause. This paper ... -
Identifying high-impact operating states in power system reliability analysis
(Chapter; Peer reviewed, 2018)The reliability of a power system depends, among other things, on the operating states of the system. For reliability analysis for long-term planning purposes, it may be necessary to consider a large set of representative ... -
