Ukrainian Journal of Physics| Резюме: | The calculation results for the dependences of the diffusion coefficient and the barodiffusion ratio on the pressure and the density in vicinity of the critical point obtained for spatially confined fluid systems are presented. The critical behavior of those kinetic properties in small volumes of fluids has been analyzed inthe fluctuation, dynamic crossover, and regular regions. Spatial dispersion effects have been taken into consideration to avoid the zero value of diffusion coefficient and the infinite value of barodiffusion ratio, when approaching the critical state. Numerical estimations that use experimental data have been made, and plotsthat illustrate our theoretical calculations have been built. |
