The present work is dedicated to the simulation of compressible two-phase flows with phase change for pool boiling type problems. The model we are concerned with involves scales that allow to distinguish the interface between both phases. The mass transfer is driven by assuming local and instantaneous equilibria with respect to phasic pressures, temperatures and chemical potentials, which enables dynamic generation of two-phase interfaces within a pure phase. We present a general numerical solver that allows to cope with any type of EOS and preliminary numerical results of nucleation with transition towards film boiling.
