As the penetration of variable renewable power generation increases in power systems around the world, system security is challenged. It is crucial to coordinate the available flexible generating resources, such as hydropower, to meet the need for system balancing. However, reserved capacity on...

CO₂ capture by dropwise CO₂ condensation on cold solid surfaces is a promising technology. Understanding the role of the nanoscale surface and topographical features of CO₂ droplet wetting characteristics is of importance for CO₂ capture by this technology, but this remains unexplored as of yet...

The research and development work towards a compact SF₆-free load break switch for the medium voltage range has led to several design proposals. The interruption capability of three different nozzle and gas flow concepts with atmospheric air as the interrupting medium is compared and assessed. The...

Soot is an important toxic pollutant generated during high-temperature incineration of solid waste (i.e., biomass and plastic waste) under air-lean conditions, and has a great impact on flame radiation. The main objective of this work is to study the synergistic effect of biomass and polyurethane co...

This study presents a single CO₂ vapour-compression system for independent cooling and dehumidification of indoor air conditioning systems. A CO₂ gas cooler outlet split (GOS) ejector system is introduced to generate two levels of evaporating temperature, and therefore indoor air temperature and...

Particulate matter (PM) has been sampled from a compression ignition engine using a differential mobility spectrometer (Cambustion DMS 500) and for imaging in a transmission electron microscope (TEM) with the aim of coupling these two measuring techniques. A known issue when coupling these two...

This study presents a novel approach for Rankine cycle (RC) analysis, introducing a generic counter current heat exchanger (HX) model to enable basic fluid thermal and flow behaviour in HXs to be considered in a cycle optimisation process. The generic HX model does not represent a certain HX-type or...
