چکیده

the model fluids containing hard ellipses (hes) and gay-berne (gb) particles where their center is moving in one dimension and confined between two parallel walls with different interactions are investigated using monte carlo simulation, nvt ensemble. the dependency of fluid pressure with respect to the wall distances is studied. the oscillatory behaviors are seen in this quantity against wall separations. the total average number density profile of particles is calculated using the angular number density. for both he and gb particles confined between hard walls the total average number density at the wall shows a similar oscillatory behavior. we also related the pressure of these systems to the relevant solvation force between two colloidal particles. we have investigated the dependency of this quantity to the packing fraction, temperature, structure of the walls confining the particles and the interaction between ellipses of the fluid. finally it is possible to reach the required solvation forces by changing the thermodynamic or structural properties.

Polymers confined between two parallel plane walls.

Single three-dimensional polymers confined to a slab, i.e., to the region between two parallel plane walls, are studied by Monte Carlo simulations. They are described by N-step walks on a simple cubic lattice confined to the region 1< or = z < or = D. The simulations cover both regions D<>RF (where RF approximately Nnu is the Flory radius, with nu approximately 0.587), as well as the ...

Phase behavior and structure of model colloid-polymer mixtures confined between two parallel planar walls.

Using Gibbs ensemble Monte Carlo simulations and density functional theory we investigate the fluid-fluid demixing transition in inhomogeneous colloid-polymer mixtures confined between two parallel plates with separation distances between one and ten colloid diameters covering the complete range from quasi-two-dimensional to bulklike behavior. We use the Asakura-Oosawa-Vrij model in which collo...

Natural Convection Heat Transfer From Horizontal Cylinders in a Vertical Arra Confined Between Parallel Walls

Laminar natural convection from an array of horizontal isothermal cylinders confined between two vertical walls, at low Rayleigh numbers, is investigated by theoretical and numerical methods. The height of the walls is kept constant, however, number of the cylinders and their spacing, the distance between the walls and Rayleigh number have been varied. The optimal spacing (confining walls) and ...

Hydrodynamic interactions of spherical particles in suspensions confined between two planar walls

Hydrodynamic interactions in a suspension of spherical particles confined between two parallel planar walls are studied under creeping-flow conditions. The many-particle friction matrix in this system is evaluated using our novel numerical algorithm based on transformations between Cartesian and spherical representations of Stokes flow. The Cartesian representation is used to describe the inter...

Melting of multilayer colloidal crystals confined between two walls.

Video microscopy is employed to study the melting behaviors of multilayer colloidal crystals composed of diameter-tunable microgel spheres confined between two walls. We systematically explore film thickness effects on the melting process and on the phase behaviors of single crystal and polycrystalline films. Thick films (>4 layers) are observed to melt heterogeneously, while thin films (≤4 lay...
