Characteristic equations for one dimensional unsteady flow: Two phase fluid
Abstract
The characteristic equations for one dimensional unsteady flow for a two phase fluid are derived. The equations governing the motion of the two phases are obtained by using the instantaneous conservation equations for each phase together with appropriate constitutive equations which define the thermodynamics, transport, and chemical properties of the phase. These equations are coupled at the interfaces of the two phases through jump conditions and interfacil boundary conditions. It is assumed that average values in the two phases can be defined and that products of averages can be taken as the average of products. In addition, since the averaged equations of the two phases are not independent, it is assumed that average values of the interation terms associated with the interfacial mass, momentum, and energy transfers can also be defined.
