A consistent reduction of the two-layer shallow-water equations to an accurate one-layer spreading model
(Journal article; Peer reviewed, 2019)The gravity-driven spreading of one fluid in contact with another fluid is of key importance to a range of topics. These phenomena are commonly described by the two-layer shallow-water equations (SWE). When one layer is ... -
Alignment and rotation of spheroids in unsteady vortex flow
(Peer reviewed; Journal article, 2021)Preferential orientations of inertialess nonspherical particles are examined through three qualitatively different stages of a time-evolving Taylor–Green vortex flow. Despite an unexpected decorrelation between the vorticity ... -
Clustering of inertial spheres in evolving Taylor-Green vortex flow
(Peer reviewed; Journal article, 2020)Clustering of inertial spheres in a statistically unsteady flow field is believed to be different from particle clustering observed in statistically steady flows. The continuously evolving three-dimensional Taylor–Green ... -
Diameter ratio effects in the wake flow of single step cylinders
(Peer reviewed; Journal article, 2020)Vortex interactions behind step cylinders with diameter ratio 2 ≤ D/d ≤ 3 at Reynolds number (ReD) 150 were investigated by directly solving the three-dimensional Navier–Stokes equations. In accordance with the previous ... -

An integral model based on slender body theory, with applications to curved rigid fibers
(Peer reviewed; Journal article, 2021)We propose a novel integral model describing the motion of both flexible and rigid slender fibers in viscous flow and develop a numerical method for simulating dynamics of curved rigid fibers. The model is derived from ... -
Vortex system around a step cylinder in a turbulent flow field
(Peer reviewed; Journal article, 2021)The vortex system around the step surface of a step cylinder with a diameter ratio D/d=2 at Reynolds number (ReD) 3900 was investigated by directly solving the three-dimensional Navier–Stokes equations. Formation mechanisms ... -
Weakly nonlinear broadband and multi-directional surface waves on an arbitrary depth: A framework, Stokes drift, and particle trajectories
(Peer reviewed; Journal article, 2021)Surface gravity waves in coastal waters are broadband and multi-directional, whose quadratic properties are of considerable engineering and scientific interest. Based on a Stokes expansion and an envelope-type framework, ...
