Abstract: The influence of ground effect on the wake of a high-speed train (HST) is investigated by an improved delayed detached-eddy simulation. Aerodynamic forces, the time-averaged and instantaneous flow structure of the wake are ...

Abstract: This study investigated the effect of air pressure on the freezing process of a water droplet on a cold surface. A common belief is that bulk liquid water is incompressible and air pressure does not affect the freezing ...

Abstract: Flow past a porous square cylinder, which is constituted by an array of small square cylinders, was studied by simplified and highly stable lattice Boltzmann method (LBM) at Re = 4000. The effects of solid volume fractions ...
