Abstract: We consider a multicomponent fluid placed in a porous medium. The Ornstein–Zernike approximation is used to calculate the pair correlation functions for density fluctuations in the mixture components. We show that light scattering in the neighborhood of the critical state of the system is determined (in the single-scattering approximation) by the commonly known Ornstein–Zernike formula. We investigate the shift in the critical parameters due to the porous medium.

Keywords: multicomponent fluid, porous medium, correlations.
