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 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.

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). 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.
