This PhD thesis is about the study of two-phase flow patterns evolution during progressive evaporation in horizontal tubes. The goal is to better understand the flow regimes inside a receiver tube of a concentrated solar power plant with direct steam generation. This technological evolution allows vapor production directly inside the solar field, which can lead to coast reductions. A two-phase liquid-vapor flow occurs inside the tube, which is currently still difficult to predict. Numerical simulation is an interesting way to investigate these complex phenomena. A model has been developed in order to simulate the flow patterns, from first vapor generation to large vapor slugs. It is based on Fluent software's two-phase VOF model, to which a...
