Anisotropic particles are common in many industrial and natural turbulent flows. When these
particles are small and neutrally buoyant, they follow Lagrangian trajectories while …

The dynamics of heavy particles suspended in turbulent flows is of fundamental importance
for a wide range of questions in astrophysics, atmospheric physics, oceanography, and …

The effects of particle inertia, particle shape, and fluid shear on particle rotation are
examined using direct numerical simulation of turbulent channel flow. Particles at the …

The motion, settling, and dispersion of microplastics in the ocean are determined by their
rotational dynamics. We present experiments on elongated, large aspect ratio, and mildly …

We consider the rotation of neutrally buoyant axisymmetric particles suspended in isotropic
turbulence. Using laboratory experiments as well as numerical and analytical calculations …

Using a numerical model, we analyse the effects of shape on both the orientation and
transport of anisotropic particles in wavy flows. The particles are idealized as prolate and …

Hydrocyclone not only achieves centrifugal separation of solids and liquids but also purifies
oil-coated particles through rotational shear flow, resulting in high-speed particle rotation …

Stretching in continuum mechanics is naturally described using the Cauchy–Green strain
tensors. These tensors quantify the Lagrangian stretching experienced by a material …

The translational and rotational dynamics of oblate spheroidal particles suspended in a
directly simulated turbulent channel flow have been examined. Inertial disk-like particles …

Motivated by applications in technology as well as in other disciplines where the motion of
particles in a turbulent flow field is important, the orientation and settling velocity of …
