Structural Models for Particles in LES: Assessment Through the Subfilter Enstrophy Field
摘要
The large-eddy simulations (LES) are increasingly often applied to turbulent flows with particles or droplets. One of the general questions refers to the impact of LES smoothing on the dispersed phase. A considerable body of evidence has been gathered over the years concerning the droplet preferential concentration, the average settling velocity in the gravity field, as well as the collision statistics [5, 8, 17].
