International audience; Based on a numerical approach, we propose in this study to characterize the interaction between a laminar boundary layer of a superheated or subcooled vapor flow and a static liquid pool at saturation temperature. For the purp

On two-phase flow solvers in irregular domains with contact line

Autor: Elena Roxana Popescu, Frederic Gibou, Mathieu Lepilliez, Sébastien Tanguy

Publikováno v: Journal of Computational Physics
Journal of Computational Physics, Elsevier, 2016, 321, pp.1217-1251. ⟨10.1016/j.jcp.2016.06.013⟩

International audience; We present numerical methods that enable the direct numerical simulation of two-phase flows in irregular domains. A method is presented to account for surface tension effects in a mesh cell containing a triple line between the
