Abstract

Solutions of simple well-defined potential two-phase flows are presented. A coefficient of added mass, the pressure difference between phases and the equation of motion of each phase are derived, for these cases, in terms of a single function, β, that depends only on the void fraction. Three specific examples are used to test recent formulations of the "two-fluid" model. Only Geurst's equations, derived from a variational aproach, pass these tests.
