To reach in-depth insight into multiphase flows.
Inhoud
In fluid mechanics, multiphase flow is a generalisation of two-phase flow, i.e. cases where the phases are not chemically related (e.g. dusty gases, particles in fluid) or where more than two phases are present (e.g. propagating steam explosions, suspensions, aerosols, sprays, clouds, ...). More general, multi-phase flow involves the interaction of solids with fluids, or of different fluids with each other and is of utmost importance in many engineering and science fields.

Each of the phases is considered to have a separately defined volume fraction (the sum of which is unity), and its own velocity field. Conservation equations for the flow of each species (perhaps with terms for interchange between the phases), can then be written down straightforwardly.

The momentum equation for each phase is less straightforward. It can be shown that a common pressure field can be defined, and that each phase is subject to the gradient of this field, weighted by its volume fraction. Transfer of momentum between the phases is sometimes less straightforward to determine, and in addition, a very light phase in bubble form has a virtual mass associated with its acceleration. (The virtual mass of a single bubble is about half its displaced mass). These terms, often called constitutive relations, are often strongly dependent on flow regime.
