An experimental investigation of the phosphorescence properties of liquid and vapour acetone is presented with the goal of introducing a novel technique for improved two-phase flow visualization. Commonly applied laser induced fluorescence (LIF) investigations of two-phase flows are challenging, in particular because of the large disparity in fluorescence intensity between the two phases and th...

Results of an experimental and theoretical investigation of heat and moisture movement in unsaturated MX-80 bentonite are presented. A thermo-hydraulic cell that allows measurement of transient temperatures and facilitates the determination of pseudo-transients of moisture content, dry density and chemical composition has been used to perform thermal gradient tests. Results of a number of tests...

Several physical properties and the isobaric vapour-liquid equilibria at 101.32, 50, 30 kPa were measured for binary system consisting of acetone ionic liquid 1-ethyl-3-methyl-imidazolium acetate. Liquid-liquid equilibrium data also temperatures from 298.15 up to 328.35 K atmospheric pressure. An hourglass-shaped miscibility gap was found. The simultaneous correlation both VLE LLE regions 101.3...

Thermodynamic theory of phase equilibrium is the main base for the development of the methods of fluid mixtures separation. Thermodynamic approach has a lot of advantages in the practical application when conditions of separation processes are close to the equilibrium. For nonequilibrium processes these advantages fail and one should use another methods including empirical relationships and mod...

BACKGROUND The loss of perfluorocarbon (PFC) vapour in the expired gases during partial liquid ventilation should be minimized both to prevent perfluorocarbon vapour entering the atmosphere and to re-use the recovered PFC liquid. Using a substantially modified design of our previously described condenser, we aimed to determine how much perfluorocarbon liquid could be recovered from gases contai...

We discuss the ground state and the small-amplitude excitations of a degenerate vapour of fermionic atoms placed in two hyperfine states inside a spherical harmonic trap. An equationsof-motion approach is set up to discuss the hydrodynamic dissipation processes from the interactions between the two components of the fluid beyond mean-field theory and to emphasize analogies with spin dynamics an...

The Enskog–Vlasov equation is a phenomenological kinetic that extends the Enskog for dense (non-ideal) hard-sphere fluid by adding an attractive soft potential tail to purely repulsive contribution. Simplifying assumptions about pair correlations lead Vlasov-like self-consistent force field adds non-local collision integral. Within limitations imposed underlying assumptions, extension gives abi...
