Boiling heat transfer region with independence of the wall temperature

Extensive measurements of the intensive cooling of hot-rolled wires with te mperatures between 1000 degrees C and 1100 degrees C are analysed. The anal ysis proves the existence of a convection-controlled boiling region, which has been previously observed by few authors in the case of high mass fluxes and high liquid subcooling. This region is characterised by an independenc e of the heat flux of the surface temperature. The heat flux depends essent ially on the Reynolds number, the main influence parameter of the single ph ase convection, and on the liquid subcooling.
