Multiphase Flow

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In fluid mechanics, multiphase flow is a generalisation of the modelling used in two-phase flow to cases where the two phases are not chemically related (e.g. dusty gases) or where more than two phases are present (e.g. in modelling of propagating steam explosions). Each of the phases is considered to have a separately defined volume fraction (the sum of which is unity), and velocity field. Conservation equations for the flow of each species (perhaps with terms for interchange between the phases), can then be written down straightforwardly.
