Variation of drag, lift and torque in a suspension of ellipsoidal particles
Powder Technology, 2018 Previous research has mostly been focused on the drag force in fluid-particle assemblies. However, when the particle geometry is non-spherical, secondary forces and torque may no longer be negligible.
