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 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 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 taken from a study of the characterization of transient distributed surface sources through infrared thermography by Vintrou, Lariqi, Bauzin and Bairi and was presented at EUROTHERM seminar 94 (Metti 5). In this work the spatial and temporal distributions of a heat flux distribution received by the front surface of a thin metal plate are inferred from the temperature distribution measured on the back face by ir thermal imaging (shown here).
