Gas-liquid two-phase flow in the axial clearance of liquid-ring pumps
In this study, the leakage flow in the axial clearance of a 2BEA-203 liquid-ring pump has been modeled through numerical simulation using the renormalization group k - ∈ turbulence model and the multiphase volume...

First-Principles Investigation on the Tribological Properties of h-BN Bilayer Under Variable Load
Using first-principles method, for h-BN bilayer, we successfully probe the major factors of different low-friction paths in the three-dimensional potential energy surface (3D-PES) under variable loads. By mean...
