Flow visualisation from PIV testing, showing vortex rollup in jet impingement study by T.S. O´Donovan (EUROTHERM Award winner, 2008). This image shows the surface temperature distribution on an electrically heated foil subject to jet impingement with enhanced swirl. It is from a paper by Kinsella, Donnelly, O´Donovan and Murray and is in the Proceedings of EUROTHERM 2008. Impinging jet full field flow velocity and turbulence intensity from PIV measurements in jet impingement study by T.S. O´Donovan (EUROTHERM Award winner, 2008). This image shows the temperature field behind a heated cylinder, measured using Laser Induced Fluorescence (LIF). The flow has a Reynolds number of 130 and a Richardson number of 1.5. This image is taken from a study by Seuntiëns, Rindt and van Steenhoven (http://w3.wtb.tue.nl/fileadmin/wtb/wtb_energytechnology/poster_Harm.pdf)
This is an image of an air bubble injected into water from a 1 mm diameter orifice at a rate of 100 ml/min. This image is captured prior to the bubbles departure from the orifice. Donoghue, Murray & Robinson, Fluids & Heat Transfer research group, Trinity College Dublin. This image is from a paper by Yildirim, Rindt and van Steenhoven in EUROTHERM 2008 Proceedings, which looks at the effect of heat input and the presence of a wire on vortex shedding behind a cylinder This image of molecular simulation of droplet evaporation is from the paper of Sumardiono and Fischer that was presented at EUROTHERM Seminar 77: Heat and Mass Transfer in Food Processing, held in Parma, Italy in 2005. This image shows pore scale simulation of heat and mass transfer in a metal foam. Plane sections: fluid velocity, solid surface and stream lines colored by solid and fluid temperature. Solid structure is reconstructed from 3D sample tomography. Simulations performed to obtain the effective (macroscale) transfer properties. IUSTI Lab/Heat and Mass Transfer team/Jean-Michel HUGO
This image shows phase locked vorticity plots for an impinging synthetic jet with a constant stroke length of 17D at different phases within the ejection and suction stages of the cycle. It is from a paper on synthetic jet heat transfer by McGuinn, Persoons, Valiorgue, O´Donovan and Murray and is in the Proceedings of Eurotherm 2008. This image depicts the evolution of a 3.8 mm equivalent diameter bubble, during its growth and departure from a 1 mm orifice, its rise and bouncing upon a heated surface. The release height in this case is 25 mm. Donoghue, Murray & Robinson, Fluids & Heat Transfer research group, Trinity College Dublin. This image shows a nanochannel with a hot wall (left) and a cold wall (right). Heat transfer in the nanochannel is simulated using molecular dynamics and Monte Carlo methods; the research has been conducted by Nidea, Frijns, van Steenhoven and Markvoort (http://w3.wtb.tue.nl/fileadmin/wtb/wtb_energytechnology/poster_Silvia.pdf). This image shows Nusselt number distributions in the entrance region of a horizontal pipe and is from Grassi and Testi in Proceedings of Eurotherm 2008 Developing flow of FC-72 in a uniformly heated horizontal cylindrical pipe was studied in the regime of transitional mixed convection. Heat transfer coefficients were measured at 6 cross sections along the heated length, with 60 azimuthal positions being monitored at each section. A significantly different thermo-fluid-dynamic behaviour was observed between top and bottom of the pipe.
