Abstract:
We solve the problem of calculating the density distribution of binary liquid components in a cylindrical pore under the action of external field. The problem is solved in the slow inhomogeneity approximation based on a phenomenological expression for the free energy of the studied system. Taking into account the expression for the general solution, we separately analyze the case of a gravitational field. We also examine the particular case of a $\mathrm{WR}$–type model system.
