Analysis of a Wide Range of Commercial Exterior Wood Coatings
(MDPI AG, 2020)This study was focused on measuring the properties of twenty-three commercially available coatings formulated for exterior wood applications. The coatings were characterized by measuring their surface tension, solid content, ... -
Analytical heat conduction model of annular composite fins
(2018)A two-dimensional analytical heat conduction model of an annular composite fin has been carried out.The composite fins composed of a porous polyethylene core, a square aluminum insert,and metallic zinc coating layers, ... -
Composite heat sink LED cooling
(2018)Metal coating of 3D printed polymers is an attractive proposition for thermal dissipation of light emitting diodes, due to its high efficiency and markedly lower material costs than conventional aluminum heat sinks. ... -
Effect of moisture condensation on vapour transmission through porous membranes
(2021)Porous membranes find natural application in various fields and industries. Water condensation on membranes can block pores, reduce vapour transmissibility, and diminish the porous membranes' performance. This research ... -
Electrospray array heat transfer
(2018)Multiple source electrospraying enables higher droplet mass flux and greater cooling coverage area in comparison with its single source counterpart. The local convective heat flux to a multiple source electrospray array ... -
Evaporating hydrophilic and superhydrophobic droplets in electric fields
(2021)Evaporating water droplets on a heated substrate are investigated in this work. Specifically, the influences of electric fields are studied in the context of the heat flux distribution beneath the droplets as well as the ... -
Fabrication of Composite Heat Sinks Consisting of a Thin Metallic Skin and a Polymer Core Using Wire-Arc Spraying
(2019)Three composite heat sinks in the shape of a disk, a cylinder, and a cylinder with vertically projecting fins were made by applying a thin (0.4 – 0.7 mm) zinc layer onto ABS polymer cores using wire-arc spraying. The ... -
Heat flux distribution beneath evaporating hydrophilic and superhydrophobic droplets
(Elsevier BV, 2020)An experimental investigation of the heat and mass transfer to an evaporating hydrophilic water droplet using thin-foil thermography and droplet shape analysis is reported. These results have been compared with that of a ... -
Heat transfer characteristics of single cone-jet electrosprays
(2017)Spray cooling is an attractive proposition for thermal dissipation due to its high efficiency and markedly lower power requirements compared with more conventional air cooling systems. The local convective heat flux to ... -
Heat Transfer Characterization of a Single Source Ultra-Low Flow Rate Electrospray
(2013)The development and optimization of two phase electrospray cooling is currently restricted,in part due to the insufficient knowledge of how the various parameters that define an electrospray interact ... -
Local Heat Transfer to an Evaporating Sessile Droplet in an Electric Field
(2016)Local heat transfer of an evaporating sessile droplet under a static electric field is an underdeveloped topic. In this research an 80 μl water droplet is placed in the centre of a 25 μm thick stainless steel substrate. A ... -
Local heat transfer to an evaporating superhydrophobic droplet
(2018)The heat flux distribution beneath a superhydrophobic evaporating droplet has been explored. High speed, high resolution infrared thermography was employed to measure the heat transfer characteristics of the evaporating ... -
Natural convection from a triangular array of isothermal horizontal cylinders
(2021)Natural convection heat transfer from three isothermally heated horizontal cylinders submerged in water in a triangular arrangement is investigated. Two configurations, named here as one over two and two over one, are ... -
A novel ultra-large flat plate heat pipe manufactured by thermal spray
(Elsevier BV, 2020)An ultra-large flat plate copper heat pipe (180 × 180 mm2) was constructed using a thermal spray technique, and it was then thermally characterized. A porous copper wick was fabricated by using a flame spray torch to deposit ... -
Plume Characterisation of a Single Source Electrospray for Micro Electronic Cooling
(2014)Development and optimization of two phase electrospray cooling is an undeveloped topic, in part due to unavailable knowledge of how the various electrical, geometrical, thermal and hydraulic parameters influence both ... -
A review of heat pipe technology for foldable electronic devices
(2021)The advent of foldable and wearable devices, such as the Samsung Galaxy Fold (2019) and Huawei Mate X (2019), require increased battery size and processor performance to drive their larger flexible displays. There is a ...
