Shevchenka, 01601, Kiev, Ukraine2 Institute of Surface Chemistry, Kiev, UkraineThe critical behavior of the susceptibility, diffusion and barodiffusion coefficients, and barodiffusionratio is studied for individual fluids and binary fluid mixtures with reduced geometry. Thefinite-size scaling hypothesis and hypothesis of complete scaling are used to examine the specificfeatures of diffusion phenomena in these fluids. Effects of the low crossover dimensionality andspatial dispersion on characteristics of diffusion processes in mesoscale fluids are studied in thecritical region. The dimension crossover for diffusion phenomena from 3D to 2D confined watersystems is analyzed.11
