A model for the simulation of complex three-dimensional free surface flows is presented. An incompressible liquid interacts with a compressible gas. The incompressible Navier-Stokes equations are solved only in the liquid domain while the dynamical effects in the gas are neglected. The compressibility effects of the gas are taken into account by computing its pressure. Surface tension effects a...

We perform Monte Carlo simulations of the hard-sphere lattice gas on the body-centred cubic lattice with nearest neighbour exclusion. We get the critical exponents, β/ν = 0.311(8) and γ/ν = 2.38(2), where β, γ, and ν are the critical exponents of the staggered density, the staggered compressibility, and the correlation length, respectively. The values of the hard-sphere lattice gas on the simpl...

[1] During sea-level drop, water and gas pressures within oceanic hydrate systems can exceed the total vertical stress and this can drive slope failure and gas venting. We investigate this behavior with a multi-phase fluid and heat flow model. During sea-level drop, fluid pressures drop much less than the total stress due to both the high gas compressibility and hydrate dissociation. In permeab...

In gas-oversaturated solutions, stable surface nanobubbles can exist thanks to a balance between the Laplace pressure and the gas overpressure, provided the contact line of the bubble is pinned. In this article, we analyze how the disjoining pressure originating from the van der Waals interactions of the liquid and the gas with the surface affects the properties of the surface nanobubbles. From...

Oil compressibility represents a significant character in reservoir simulation, design of surface facilities and the analysis well tests, specifically for systems below bubble point pressure.

A phantom network of Gaussian chains far from the point of gelation can be described as a gas of interacting particles represented by the cross links. The type of particles varies with the network functionality, whereas the type of interaction depends on the properties of the connecting chains. In a mean field approximation the Equation of State can be calculated using Mayer’s cluster expansion...

A non-linear model of an adjustable automotive damper is developed, which includes the compressibility of the ̄uid, trapped gas and expansion of the cylinder. The parameters for the model are selected by ®tting the model to experimentally obtained data from the damper. The model is shown to give an excellent representation of the damper under investigation. The performance of the damper model i...

the thermal diffusion factor, at, for a binary gas mixture is calculated on the basis of nonequilibrium thermodynamics. a new formula for at is derived and this factor is given for several paris of gases according to this formula.

We introduce a structural quantity to probe the glass transition. This quantity is a linear generalized compressibility which depends solely on the positions of the particles. We have performed a molecular dynamics simulation on a glass-forming liquid consisting of a two-component mixture of soft spheres in three dimensions. As the temperature is lowered (or as the density is increased), the ge...
