Abstract
Numerical simulation of phase change and contact lines on unstructured grids: towards simulation of nucleate boiling
Highlights
Two-phase flows are found in various natural phenomena and industrial applications
Most of the applications are interested in nucleate boiling, a regime for which vapor bubbles are nucleated on the heated surface and detach afterwards due to buoyancy effect
Numerical simulation of nucleate boiling requires to compute accurately the amount of liquid transformed into vapor and must take into account the surface wettability effects which can be determining on the global heat transfer
Summary
Two-phase flows are found in various natural phenomena and industrial applications. boiling is widely used for heat exchanges in nuclear plants or in refrigerating machines. Keywords Boiling, Unstructured mesh, Conservative level-set, Contact angle, Drop impact. Heat conduction induces phase change at the liquid-vapor interface, creating physical discontinuities.
