Thermodynamic of two-phase two component compressible fanno type flow

摘要

The behaviour of an adiabatic two-phase gas-liquid flow through a duct with a constant cross-sectional area is studied from a thermo- dynamics point of view. By assuming the two-phase mixture as homogeneous, the treatment of the physical conservation laws makes it possible to obtain an analytical equation of the fluid evolu- tion which expresses the difference between the Fanno and the isothermal evolutions. On the basis of its differential form and the second principle of thermodynamic, the properties of this flow are discussed.
