Relaxation and short time dynamics of bulk liquids and fluids confined in spherical cavities and slit pores

Article Abstract:

The density of states for bulk and confined fluids modeled uses a proposed gamma distribution resulting in a closed form analytical expression for the velocity autocorrelation function and the relaxation time of the fluid. The gamma model is applied to a bulk soft sphere liquid and fluids confined in a spherical cavity and slit-shaped pores.

Mesoscopic multiparticle collision dynamics of reaction-diffusion fronts

Article Abstract:

A mesoscopic multiparticle collision model for fluid dynamics is generalized to incorporate the chemical reactions among species that may diffuse at different rates. The model is also able to incorporate the effects of molecular fluctuations on the reactive dynamics.

Equilibrium dynamics of the toy model of dense fluid: The infinite damping limit

Article Abstract:

The equilibrium dynamics of toy model of dense fluid in the infinite damping limit is investigated. It is found that slow dynamics and the dynamic transition in the model are distinct from those in the idealized mode coupling theory.
