Abstract

In order to facilitate the analysis of multiphase, multicomponent flows, a new method has been developed which reduces the equations for variable cross-section flow to equations for constant cross-section flow at the expense of making energy and momentum exchange terms somewhat more complicated. This method is valuable because all transient multiphase, multicomponent flows are inherently variable cross section flows which are more difficult to compute than constant cross-section flows. The new method involves the division of all conservation equation by a constant reference area the value of which is arbitrary. This method has been successfully used in the development version of the Material Dynamics (MDYN) module of the European Accident Code (EAC).
