Dancing Particles in a Pipe: Which Model Is More Accurate? ⚡ экспресс
Original: "Effects of Turbulence Modeling and Parcel Approach on Dispersed Two-Phase Swirling Flow"
Scientists compared computer simulations of swirling particle-laden flow and found that a simple model outperforms the latest ones.

Air mixed with particles swirls in a pipe like coffee grounds in a cup. After comparing three computer models, scientists found the good old 'standard' one more accurate than the trendy ones. To save time, they bundle particles into 'parcels' — with almost no loss of accuracy. Now engineers can design filters and dryers faster.
🎯 Cyclone dust collectors, based on this principle, can separate particles just a few microns across — thinner than a human hair.
