Numerical simulation of boiling during the quenching process

Abstract

National audienceDuring the thermal modelling of the quenching process, different stages of boiling need to be treated, from nucleate boiling to generation and growth of a vapour film. The interface between each phase flow is determined using a level set method. Surface tension is evaluated using the continuum surface force. The proposed approach demonstrates the capability of the model to simulate detachment of a single bubble and the generation of film vapour from a heated source. A comparison between numerical and experimental results shows a good agreement.br/>See http://hal.archives-ouvertes.fr/docs/00/59/26/76/ANNEX/r_71D43983.pd
