عنوان انگلیسی Solvation Force of Ellipse-Shaped Molecules Moving in One Dimension and Confined between Two Parallel Planar Walls
چکیده انگلیسی مقاله 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.
