Adsorption of fluids on hard wall: Application of inhomogeneous pair correlation function

2216-2222The local density of non-uniform fluids is important in understanding fluid behaviours in contact with the planar walls or slit like pore. The density profile of the fluid near the hard wall is obtained starling from the direct correlation function defined by Ornstein-Zernike equation with Percus Yevick analytical solution. The bridge function, which is useful to obtain the cavity function or radial distribution function, has been calculated. In the case of outside the hard sphere core, the mean spherical model approximation (MSMA) has been used to calculate the direct correlation function. The adsorption of a model Lennard -Jones fluid near a hard wall has been calculated. The results obtained for the generalized adsorption and agree well with the standard results
