The elasto-inertial focusing and rotating characteristics of spheroids in a square channel
flow of Oldroyd-B viscoelastic fluids are studied by the direct forcing/fictitious domain …

We investigate the hydrodynamics of a spherical and dumbbell-shaped swimmer in a
viscoelastic fluid, modelled by the Giesekus constitutive equation. The 'squirmer', a model of …

Self-propelled particles are commonly found in a large number of planktonic organisms such
as bacteria, fungi, and algae in nature, and researchers have taken a long interest in …

The classical paper by Lighthill (Commun. Pure Appl. Maths, vol. 109, 1952, p. 118) on the
propulsion of ciliated microorganisms has become the reference against which many …

We simulate a spheroidal swimmer through a complex fluid, modeled by the Giesekus
constitutive equation incorporating fluid inertia. We develop a spheroidal swimmer model …

The “squirmer model” is a classical hydrodynamic model for the motion of interfacially driven
microswimmers, such as self-phoretic colloids or volvocine green algae. To date, most …

In this study, we used a three-dimensional lattice Boltzmann method to simulate the settling
motion of a spherical squirmer in a square tube under the effect of gravity. A spherical …

The vision of deploying miniature vehicles within the human body for intricate tasks holds
tremendous promise across engineering and medical domains. Herein, optimal navigation …

We simulated the transport features of a delivery system, which forms by an elliptical
squirmer (a type of active particle, driven by an imposed tangential velocity at its boundary) …

The swimming performance of rod-shaped microswimmers in a channel was numerically
investigated using the two-dimensional lattice Boltzmann method (LBM). We considered …
