Abstract

It is known, that the phenomena of phase change and the boiling crisis are not yet fully deciphered, which leads to the generation of technical problems, such as frequent breakdowns and accidental shutdowns in thermal installations. The main objective of this study is the numerical analysis of an ascending flow during boiling in a vertical channel by the Relap5/Mod3.2 code. This code can helps in the analysis heat transfer by convection, boiling, condensation and even by radiationin steady state or in transition regimes. The validation was made by comparing our results of simulationwith the experimental results under the same conditions (pressure, mass flow, diameter and flux density). This analysis allowed us to determine the different regimes of heat transfer along the channel, as well as the conditions of appearance of the boiling crisis.
