Theoretical and experimental investigations in recent years in the field of dispersed two-phase flows have repeatedly emphasized the significance of new variables like velocity fluctuations associated with individual phases, dispersed phase pressure, dispersed phase correlation functions etc? in controlling the mechanics and transport properties of the underlying flows. This calls for reviewing what has been learned from classical and/or statistical thermodynamics of molecular mixtures and outlining the appropriateness of extending this to dispersed two-phase flows. There has been some notable effort in this direction in recent years, which will be reviewed in the talk with applications to bubbly liquids and fluidized beds.
