چکیده مقاله:
The direct correlation function plays an important role in liquid crystals. It is important for describing the effects of the structure of particle systems with respect to light diffraction, x-ray diffraction as well as transmission and transmission fluctuations of radiation through a dense suspension. Density functional theory is used to study confined two-dimensional molecular fluids. The approximate density functional used here is based upon a functional Taylor series expansion of the excess grand potential about the density of a uniform molecular liquid. The required direct correlation function is obtained using Percus-Yevick (PY) and Hypernetted chain (HNC) approximations for low and high number density, respectively
