Dynamic properties

To elucidate these issues, a detailed study of the microstructure of amorphous V2O5 under pressure was needed. The spatial distributions of atoms, the link distributions and the geometrical distributions of the free volumes need to be fully investigated. The distribution of free volume in the amorphous V2O5 network also needs to be visualized. These are the main contents in this paper.

Crystalline structure of CaO-P2O5-SiO2 system at 3,000 K were investigated by molecular dynamic simulation. The models with different concentrations of P2O5 (5-40 mol%) were constructed by using Born-Mayer-Huggins potentials. The size of models was from 5,270-5,520 atoms. The local environment of elements and glassy-network structure were investigated in detail.

In this research, a prototypical polymer system reinforced by a Silica nanoscopic inclusion is considered. Molecular Dynamics (MD) simulations are performed and used to characterize the conformational properties of the polymer chains in the neighborhood of the inclusion. It is shown that these chains are characterized by a specific tangential orientation which, together with the density profile and variations in chain mobility, allows for the geometric definition of the interphase region.

This paper utilizes numerical simulations to explore the influence of flow characteristics, fluid properties, and geometric parameters of the contraction microchannel on the velocity of droplets while they are in a stable state. The findings indicate that the droplet velocity is influenced by factors such as viscosity ratio (λ), capillary number (Ca), and contraction ratio (C).
