Abstract Boiling heat transfer process is important because it is a way to increase the flux density transmitted at low temperature differences. To quantify the
thermal exchanges, we performed an experimental study of the nitrogen pool boiling, in transient conditions, on a horizontal brass ribbon for a fixed
flux density. The results show that there is no break between the monophasic convection zone and the nucleated boiling region. In the nucleated
boiling zone, the temperature variations are very small. We also note that the overheating required to trigger boiling increases with the time delay
after the activation of nucleation sites. More >
