Conservation of Momentum

  • Nikolay Ivanov KolevEmail author


As in Chapter 1, from the large number of formulations of the conservation equations for multiphase flows, local volume averaging as founded by Anderson and Jackson, Slattery, andWhitaker was selected to derive rigorously the momentum equations for multiphase flows conditionally and divided into three velocity fields. The heterogeneous porous-media formulation introduced by Gentry et al., commented on by Hirt, and used by Sha, Chao, and Soo, is then implanted into the formalism as a geometrical skeleton. Beyond these concepts, I perform subsequent time averaging. This yields a working form that is applicable to a large variety of problems. All interfacial integrals are suitably transformed in order to enable practical application. Some minor simplifications are introduced in the finally obtained general equation and working equations for each of the three velocity fields are recommended for general use in multiphase fluid dynamic analysis.
