Bose–Einstein-Type Distribution for Nonideal Gas. Two-Liquid Model of Supercritical States and Its Applications

In the present paper, the spinodal is constructed by using the values of the isotherm of a new ideal gas at the point $\mu=0$ and as $\mu=-\infty$ on the ($Z$, $P$)-diagram. For a nonideal gas, a generalization of the type of Bogoliubov–Vlasov self-consistent field is given if the potential of pairwise interaction is known. A “two-liquid” model of the supercritical region, i.e., a superfluid “liquid” (molecules–monomers) and a normal “liquid” (clusters), is constructed. An application to the transport problems is given.
