We present a validation study for the hybrid particle-mesh vortex method against a pseudo-
spectral method for the Taylor–Green vortex at ReΓ= 1600 as well as in the collision of two …

Scalable and efficient numerical simulations continue to gain importance, as computation is
firmly established as the third pillar of discovery, alongside theory and experiment …

Bubbly turbulent flows involve complex interactions between bubbles and vortices, in which
their size ratio plays a critical role. The present work investigates an idealization, namely, the …

Direct numerical simulation is used to study the temporal development of single vortex rings
at various Reynolds numbers and core thicknesses. Qualitative differences between the …

In this article we propose and validate new remeshing schemes for the simulation of
transport equations by particle methods. Particle remeshing is a common way to control the …

A flow simulation was performed for face shields to investigate whether varying a shield's
edge shape could prevent droplets from entering the shield. Face shields with two types of …

We simulate and analyze the evolution of a rectilinear vortex tube with initial axial core-size
perturbations at circulation-based Reynolds number of 5000. The initial variations in the …

A computationally efficient method for solving three-dimensional, viscous, incompressible
flows on unbounded domains is presented. The method formally discretizes the …

Past experimental and numerical studies show that when two identical circular vortex rings
of moderate Reynolds number collide head-on, vortex ringlets are generated around the …

The interactions between a vortex ring and a gas bubble released at the axis are studied
numerically, which shed light on understanding more complicated bubble–turbulence …
