A multiphase system is one characterized by the simultaneous presence of several phases, the two-phase system being the simplest case. The analysis of multiphase systems can include consideration of multiphase flow and multiphase heat and mass transfer. Based on the phases that are involved in the system, phase change problems can be classified as: (1) solid-liquid phase change (melting and solidification), (2) solid-vapor phase change (sublimation and deposition), and (3) liquid-vapor phase change (boiling/evaporation and condensation).
