    • 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 ...

    • Bubble enhanced heat transfer from a vertical heated surface 

      MURRAY, DARINA BRIDGET (Taylor & Francis, 2008)
      A rising bubble in a liquid can greatly enhance heat transfer from heated surfaces by acting like a bluff body, displacing fluid as it moves and via the wake generated by the bubble, increasing the mixing of the liquid. ...

    • Control of Grinding Temperature by High Speed Air Jets 

      TORRANCE, ARCHIBALD ANDREW; MURRAY, DARINA BRIDGET; BABIC, DARKO M. (Bled, 2004)
      Grinding, like other abrasive processes, may generate high local temperatures along the arc of cut. These can cause various forms of surface damage in the most sensitive finishing phase of the manufacturing cycle. Traditional ...

    • Heat transfer characteristics of swirling impinging jets 

      PERSOONS, TIM; MURRAY, DARINA BRIDGET (ASME, 2009)
      Impinging jets are used in a wide number of industrial cooling applications due to their high heat and mass transfer abilities. The current research is concerned with the effect of swirl on the heat transfer characteristics ...

    • Particle sizing and flow measurements in an atomising mist jet nozzle: a Shadowgraphy approach 

      PERSOONS, TIM; MURRAY, DARINA BRIDGET (2010)
      Particle sizing and velocity measurements are undertaken in an atomizing water mist jet impinging onto a heated copper plate. This study forms part of an investigation into the heat transfer and flow field obtained from ...
