Flow visualisation from PIV testing, showing vortex rollup in jet impingement study by T.S. O´Donovan (EUROTHERM Award winner, 2008). 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. 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 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)
