From shape to behavior:A synthesis of non-spherical particle dynamics in air
《Particuology》2025年第1期218-243,共26页Lipeng Lv Bin Zhao 
Particles suspended in air are often non-spherical shapes, giving rise to shape-dependent complex dynamical processes. Suspended non-spherical particles are associated with a wide array of engineering and scientific s...
