Extensive research has been carried out in the past to estimate bulk viscosity of dense monatomic fluids; however, little attention paid same dilute gas regime. In this work, we perform precise Green-Kubo calculations molecular dynamics simulations argon gas. The investigated temperature and pressure range is 300 750 K 0.5 1.5 bar respectively. It observed that estimated $O(10^{-10})$ Pa s, whi...

The dynamics and structure of water at hydrophobic and hydrophilic diamond surfaces is examined via non-equilibrium Molecular Dynamics simulations. For hydrophobic surfaces under shearing conditions, the general hydrodynamic boundary condition involves a finite surface slip. The value of the slip length depends sensitively on the surface water interaction strength and the surface roughness; heu...

Compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. To calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. A new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...
