  We further probe the Discrete Boltzmann Modeling(DBM) of the single-component
two phase flows or the liquid-vapor system. There are two kinds of
nonequilibrium effects in the system. The first is the Mechanical
NonEquilibrium(MNE). The second is the Thermodynamic NonEquilibrium(TNE). The
MNE is well described in the traditional fluid dynamic theory. The description
of TNE resorts to the gas kinetic theory. Since based on the Boltzmann
equation, the DBM makes possible to analyze both the MNE and TNE. The TNE is
the main discussion of this work. A major purpose of this work is to show that
the DBM results can be used to confirm and/or improve the macroscopic modeling
of complex system.
