Stochastic modelling has already been developed and applied for single-phase flows and incompressible two-phase flows. In this article, we propose an extension of this modelling approach to two-phase flows including phase change (e.g. for steam-water flows). Two aspects are emphasised: a stochastic model accounting for phase transition and a modelling constraint which arises from volume conservation. To illustrate the whole approach, some remarks are eventually proposed for two-fluid models.
La modélisation stochastique avec point de vue lagrangien a déjà été développée et appliquée au cadre des écoulements monophasiques et des écoulements diphasiques incompressibles. Cet article propose une extension de ce formalisme aux écoulements diphasiques compressibles avec changement de phase (de type eau-vapeur par exemple). Lʼaccent est mis sur deux aspects essentiels, dont la formulation est nouvelle en modélisation stochastique : un modèle de changement de phase et lʼexpression dʼune contrainte portant sur la conservation du volume. Enfin, à titre dʼexemple, des éléments de réflexion sont présentés pour deux modèles bifluides.
