(correct me if i'm wrong). Homogeneous multi-component flow is a type of flow we consider by assuming that all participating species making up the mixture are mixed at the molecular scale and they all share the same velocity and pressure, hence also temperature. When using this assumption, convection and diffusion are the main modes of mass transfer. On the other hand, multi-phase flow is a more complex case, since the various species are mixed at larger scales and each phase has its own solution field. hope that answers. chi
