  • A Bridgman Furnace Front Tracking Model 

    Mooney, Robin Patrick (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2015)
    The Bridgman furnace is widely used in industry and research, mainly because it provides a means to directionally solidify materials in a controlled manner, so that the resulting microstructure, and hence material properties, ...
  • Air jet cooling of brake discs 

    MURRAY, DARINA BRIDGET; TORRANCE, ARCHIBALD ANDREW; MURRAY, DARINA BRIDGET; TORRANCE, ARCHIBALD ANDREW (Institution of Mechanical Engineers, 2008)
    This paper reports on an investigation of a novel approach to the cooling of brake discs, based on the application of impinging air jets. This has the capacity to enhance the heat transfer coefficients at the disc surface ...
  • Composite heat sink LED cooling 

    Gibbons, Michael; Feng, C.; Chandra, S. (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. ...
  • Electrospray array heat transfer 

    Robinson, Anthony; Gibbons, Michael (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 

    Gibbons, Michael; O'Shaughnessy, Seamus (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 ...
  • Heat flux distribution beneath evaporating hydrophilic and superhydrophobic droplets 

    Gibbons, Michael (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 

    Robinson, Anthony; Gibbons, Michael (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 ...
  • High dynamic range particle image velocimetry applied to heat convection studies 

    PERSOONS, TIM (2014)
    Convective heat transfer occurs in a wide range of engineering applications, from nuclear reactors to portable electronic devices. Accurate whole-field turbulence and flow measurements are crucial to understanding convective ...
  • Local Heat Transfer to an Evaporating Sessile Droplet in an Electric Field 

    Robinson, Anthony; Gibbons, Michael (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 

    Robinson, Anthony; Gibbons, Michael (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 ...
  • Quantum heat statistics with time-evolving matrix product operators 

    Eastham, Paul; Mitchison, Mark T.; Popovic, Maria; Goold, John (2021)
    We present a numerically exact method to compute the full counting statistics of heat transfer in non-Markovian open quantum systems, which is based on the time-evolving matrix product operator algorithm. This approach is ...
