Based on the three-dimensional viscous, steady, incompressible NS equation and the standard k-ε two-equation turbulence model, this paper establishes a three-dimensional static fluid calculation model for the vacuum pipeline ultra-high-speed train,…
Drag reduction mechanism of alpha olefin in crude oil had been investigated in study. Molecular dynamics simulations and quantum chemistry calculation at molecular level based on density functional theory were carried out. By investigation to…
