Benchmarks and numerical methods for the simulation of boiling flows

Abstract : Comparisons of different numerical methods suited to the simulations of phasechanges are presented in the framework of interface capturing computaions on structured fixed computational grids. Due to analytical solutions, we define some reference test- cases that every numerical technique devoted to phase change should succeed. Realistic physical properties imply some drastic interface jump conditions on the normal velocity or on the thermal flux.The efficiencies of Ghost Fluid and Delta Function Methods are compared to compute the normal velocity jump condition. Next, we demonstrate that high order extrapolation methods on the thermal field allow performing accurate and robust simulations for a thermally controlled bubble growth. Finally, some simulations of the growth of a rising bubble are presented, both for a spherical bubble and a deformed bubble.
