Accurate prediction of the convective single- and two-phase heat transfer is very important in process and power engineering for safety, reliability, and efficiency. In this aspect, boiling is particularly interesting and complex phenomena, which may significantly enhance the heat transfer from the heated surface to the coolant flow. The detailed understanding of these phenomena is of great importance and, as such, is put under investigation in the THELMA laboratory (Thermal-Hydraulics Experimental Laboratory for Multiphase Applications) at the Reactor Engineering Division at Jožef Stefan Institute (Slovenia).
